Anybody ever install one of these kits? What kind of results/gains did you get after installing this kit? Does any machining or anything need to be done to the motor in order to install one of these? http://shop.enginekits.com/osb/itemdetails.cfm?ID=341

I bought their forged 383 kit. it was a good kit for the money. I think you will need your block bored .30 over to make it a 335. there are a few on here with that kit, see if they post up

My block is already bored .030 over. Can I just find the right set of rods and a crank then to make it a 335 or would I be better off just buying the complete kit?

Buy a roller block 350 instead for the same price and have more power and more torque. Stroking a 305 is a waste of money and a waste of a good crank. Please search, this topic has been beat to death.
The biggest problem with a 305 is the small bores. There are only a couple good heads that fit, while there are a dozen available for a 350 that flow better.

there is a guy on here, 335 something is his user name. he has basic bolton's and that powerhouse kit. i think he go's mid 13's.. last time i checked that was a bit faster than a bolted up l98. put a power adder on and u got a tire shredding torque monster. imo anyway..

and also... all 350 heads bolt up to 305's. that kit with say l98 aluminum (vette) heads ( which could be found very cheap) and the proper cam and valvetrain. and of course the tranny and gears to match..

No, get a 350 instead. You'll be money and HP ahead.
Tunedport335 is one of the few who's done the 335 setup. Ask him, but last I checked he regrets it, and wished he did a 350. I think he got a best of 13.4. There are many TPI guys on here with bolt-on 350's doing high 12's. Kevin is one of them right there.

yeah, he went low 13's but that car was capable of more i think. He still had 2.73 gears yet still cut 1.73 60 foots i believe it was. 3.42's would have broke 1.6x and he would have had a chance at 12.9's in the right weather.

BUT my bolt on L98 has gone 12.90's so yes a 350 will run abit better on average.

But then again there are several guys on here with fairly fast 305's, so its possible to make a 335 a strong running car... its just that a 350 would be faster for the same mods

the question wasnt 305 or 350.. he said i have my lb9 apart right now, and im building it... are the powerhouse 335 stroker kits any good? i answered his question.. the answer is yes. if he asked what could make more power a 305 or a 350 it dosent take a rocket scientist to know the answer would be 350.. GOOD LUCK WITH YOURE BUILD!!!

Obviously everybody knows that a 350 will produce more power, especially with the stroker kit.

I have read quite a few different articles on the 335 stroker when I had my 89 Formula, and they can make great power with the right heads and cam setup.

Yea, you can't really say "so and so went xyz fast with abc cubes". Yea, so what? Statiscally speaking you can get more HP with more cubes, end of story.

If he was rebuilding a 305, i'd recommend leaving the rotating assembly alone. Dollar for dollar, stroking a 305 isn't a good use of money. I'd rather put the money into exhaust, camshaft, intake manifold, head modifications, etc, long before i'd think about stroking it.

If your 305 crankshaft/rods/pistons are bad and require replacement, then you have to step back, crack open a fresh bud, and have a nice long THOUGHT about what you're doing and what it's going to cost. If it goes well, you'll end up realizing what everyone else does - "Gee, I may as well just grab the 350 block and keep going from there".

8T9 - I don't think these boards are the place for your personal political preferences. Nobody here cares.

well the stroker kit will net him more torque than the 305 and wont gain that much more hp than a similar 305 build, considering the head options for that car and the bore size. Its the torque that makes it worth it tho, since 305's could always use more torque.
That will make a stronger running car.


You could probly get away with reusing stock 305 crank to save some money to put towards other things, but that kit isnt a bad deal at that price. Your just gonna have to clearance the block probly to fit the longer swing of that crank, but maybe not.

As far as good heads go, your stock 081's will respond well to a port job but the compression will be up, maybe a tad high for iron heads. You may consider 083 heads to keep compression down. Else if you can afford it, full ported aluminum L98's or trickflow small bore 175cc heads.

Vortecs are another good option it seems, you just need a vortec TPI base or w/e manifold you choose

A HOT 335 build would be a vortec headed stealth ram build. extra stroke will make up for the torque lost with the HSR, but you'll be able to rev that thing easily to 6000 rpms. Run a cc503 cam and run down stocker/bolt on LS1 cars all day long. That should easily be a mid high 12 second car if setup right.

orr89rocz, i think youre right about the stroker build. this spring im procharging my car. next winter i may use the 335 kit and vortec heads. with the boost and supporting mods im looking at a mid 11sec 305.. maybe faster with great tuning.

sonix- chill dude, youre a canadian, nobody cares about youre political corrupt views..

that statement right there is pretty uncalled for.

all the posts mentioning the 350 swap are just trying to point the guy in the right direction. some people like dumping money into a 305, to most it's just a waste. the 350 will always make more power then a 305 part for part. the 350 parts are just as cheap, and there is a much larger aftermarket for parts.

i think we all know this.. i just answered the kids question. why do these threads always turn into a flaming party.. and people like you always tend to jump in at the end to throw in youre two cents by saying something everybody on here already is aware of. if we cant help the person asking the original question, then one should not bother reponding.

if everybody knows it, then why do people continue to dump money into a waste of time 305? nobody was flaming him at all, you're the one that starting flaming other people for recommending he just swap to a 350 and be farther ahead. do you have experience with a 335? no. do you have experience with that exact kit? no. so why did you respond when you have no first hand knowledge of what he's asking?

i told of another member on here that does. and the 1/4et he runs for some insight. and then orr89roc chimed in with the exact details of that same member. so YES we helped answer the guys original question.. thats what the boards are for. help and information about thirdgens.. so lets please get back to the topic!

smart thing to do: if you have to replace the crank and rods, just build a 350, these guys are right on with that.

but...who always wants to do the "smart" thing? i'm one of the guys that keeps throwing money into a "waste of time 305", well...not so much money into the motor as the rest of the car and getting it well setup. if you want something cool, different, a neat conversation piece at a cruise in, etc, the 335 is not a bad idea, just know that you're not building the best motor for total power. i mean, look at all the guys that build weird combos like Fagoul supercharged Flatheads and weird stuff like that. (guy in our local scene has one in a little two seater roadster)

build what you want. most HP:$$$ ratio; build a 4" bore based motor. most head scratching confusion in the staging lanes when you just clicked off a 12.39 with an all motor iron headed 305; build a 305.

I won't get into my wild and crazy communist/socialist/crazy canadian political views, because this isn't the place for it Besides, politics and religion typically make any conversation go sour.

The 305 vs 350 debate will rage on long after either one is still made. (huh, that'd be now I guess...)

I just think that for the price of the stroker combo, you can get more HP by spending that money on something other then the crank/pistons he'd need.

And when the guy with basically the fastest 305 on the boards (NA) is suggesting a 350......

I do believe the original poster was looking at the gains to be had, there's more gains to be made with a 350 and seeing as how you'd have to clearance the block for that stroker crank, doesn't make much sense. Can you? Yes. I'd travel a different path myself.

Yes they do, but the best heads for small block chevy's are made for 350's and larger cubic inches with 4" bores. The heads made for 305's small bore are smaller and dont flow as well, because the 305, even stroked, does not flow as much air. There is nothing wrong with building a 305. However, once you have to replace parts such as the pistons, crank, or rods, it becomes more advantageous to just get a 350 engine.

And for those few 305's that run fast, just imagine how much faster they'd be with more cubic inches. We build 350's because they're the best bang for the buck, but you'll always go faster and make more power with more cubic inches. Or even a big block chevy, but that's a whole other topic. We laugh at imports because of their small engines and lack of power, yet some people think its cool to build small size chevy engines. I dont get it.

i think ppl tend to under-estimate the little 305. there is alot more to be had there just not many ppl are experimenting with it.

YES, 350 will make more power but i think a 305 has more than enough power capabilities to suite the needs of most street driven fbodys. its capable of 12's, it just takes the right combination of parts.

I hope to build a 305 as a second car just to show this point once my 383 is done and when i get more cash to afford a project car

If I had the money to build a 335 I'd do it in a heartbeat just for the sheer giggles factor. Money is money, you can always make more of it. If it's your motor I say screw what everyone says and do it. And if you don't like the out come, build something else.That's what this hobby is all about to me, trial and error. The experience alone is worth it to me.

Yes I know a 350 will always make more power than a 305 but my motor is a 305 and thats all I have to work with. One thing i really want to know is a rough figure of the power that this kit will give me such as how much hp or how much torque?

that will depend on how much cam and how good your heads/intake/tune is.

that could make 250hp on motor with stock stuff or up to 500 with a radical set of heads/cam/intake etc. Who knows

I would say a full bolt on 335 with stock L98 cam and heads will make near 300 hp on motor and run low 13's. its pretty much close to a L98 at that point but alittle weaker due to the smaller bore and 15 cubes less.

stick in a good cam with a good intake like the HSR or full aftermarket TPI with some siamesing and ported base, and you can see 330 or so with mild cleaned up 081/083 heads. Good heads (medium ported stockers or aftermarket) and that setup can make 350hp. great heads, bigger cam still, you may see 375hp+.

Finding a 350 to "work with" is a lot easier than clearancing a block for a stroker crank.

How much more power? Take the difference in factory figures for HP ratings on a 305 and 350 TPI and multiply that by 2/3, and add that to the 305 HP rating.

a 305/335 really isnt that small of an engine... and to think that all of you would dog on someone cuz hes not doing wut you think is right is wrong in itself... I could dog on you for saying build a 350 cuz i could go build a 455 or 5xx... but as sum1 mentioned thats a different story, so lets keep it that way... im going to bring up something that I hate to but its worth it in this situation... 4.6 supercharged svt, stock at 12.9 and thats on 10lbs of boost, but 19 cubes smaller... 385hp/385tq i beleive... its about american muscle, not about making the biggest engine possible guys... if you would do your research you would find several 305 11 second n/a cars. wut it allcomes down to is the right combination of parts, or know how to customize your own setup the right way... Anyway, if your thinking about a 335 stroker kit, go for it if that is what you really want. Just learn from the others mistakes with their slapped together setup.

"you could get a 350 for the same price" OKAY someone tell me where the hell you are going to get a new 350 roller shortblock for 599??? cos i need one and theyre ****ing expensive

I was thinking about doing a 335 stroker kit a long time ago until a friend of mine had a 305 block laying around to drop in a Regal. He decided to buy the 335 stroker kit. It was top notch quality, but the extra machine work that was involved could have bought a 350 blockand rebuild kit. Maybe if I was financially in trouble and needed to rebuild a 305 I would only if it only needed rings and bearings. If you need a new crank, etc. then I say go 350. Trust me, even he wishes he would have went 350.

We buy used 350 roller engines with under 50k miles on them for <$500 all the time here in SoCal. They usually come out of 96-99 trucks. A new set of rings and a hone and they're ready to drop in with your choice of heads and cam.

you can find 350 blocks for 100 bucks. send it to the machine shop for a little work and it's back for another 200. then all you need are a decent set of rods, another 50-100 bucks. throw in a hyper rebuild kit from a place like summit racing and you're ready to go. my hyper rebuild kit was only 400 including tax, it included the gaskets and the bearings also.

or you could go another route. since you're gonna need to have the block clearanced anyways if you go 335, just go 383. you can get 383 kits off ebay for 700 bucks. these kits include new balancer and flexplate, crank, rods, pistons, bearings. all you need are gaskets.

Regardless of who has a good opinion or bad opinion, why argue at all? Why can't the guy build a 335 if he wants to? I'm not gonna claim to know anything about what you guys are talking about right now, but I do know I went the route of a 350 because I WANTED to not because everyone told me I shouldn't build my 305. I at one point wanted a 327 based solely on the fact that I think they sound cooler, both the way the motor sounds, and the way the name rolls off my tounge . Either way, the guy wants to build a 335 then well thats his perogative and not our choice to make. He didn't ask "should I build a 335 or a 350", he asked about the 335. Done deal. And as for the dude bringing up canadian politics..... well man you were all good till you said that lol.

stock for an 85 tpi is 215 hp and 275 tq. going to a 335 will probably give you roughly around 3 hp gain and around 37 tq gain. that's by just adding the more cubes.
----------
i could honestly care less what the guy wants to build, it's his money. he keeps mentioning power, not that he wants to build it for the "be different" factor. you said you liked the 327 for the sound and just the way you say "327", that's fine. the original poster has talked about one thing in this thread... POWER.

that's with 19 cubes less and a SUPERCHARGER. and you could go ahead and bring up the big block comment. just remember to mention you'd have to change alot of other things, like going to custom headers, a different tranny, different springs, new motor mounts. you don't need all that with a 350.

yeah he talked about power,, power from a 335. that was his question.. all u guys have gone retarted. read my post #15 and #17.. and ill even say this again. if you cant answer the question asked by the member posting it. then dont bother writing some irrelevant b.s. because it makes you fell superior.

Duely noted.
----------

trying to explain to him that for the same price, or close to it, he could have more power and have a 350 for future upgrades doesn't make us "fell superior". excuse us for trying to point a fellow 3rd genner in the right direction. if we're so "retarted" then answer me this one simple question. if I were to hand you 2 assembled engines, one being a 350 and one being a 305, which one would you take?

i would of course take the 350. ive modded the hell outta my car with its original 42k 305. but when she goes pop. i may do a 335 with vortec or 113 heads. or a 355 with some better aftermarket heads, either block i decide it will be built forged and to handle boost. but thats me.. all im trying to say is, if anyone ask's a question about a specific anything. we should just help that person. not always come out with a common sense frase " 350's are better" we all know this already. and if youre not familiar with what the persons aking about, dont respond...

I think itd be cool to have a 335, seperates you from the crowd.

Yah separates you from them because you're falling behind, and you cant keep up.

I would leave the 305 alone, I've been throwing good parts in my 305 for awhile until i get a 350 and you don't get half the power from them on the 305 as you do the 350, Right now I got the 416 H.O heads, holley 750dp, Performer RPM, fresh delco-remy distributor with MSD wires, dual 3" exhuast, and a mild cam, and i would be very impressed if I had over 250hp, Now if i took everything off the 305 and put it all on a 350 I would have a much faster engine. You can find 350 engines easier then you can find thirdgens in the paper and most of the time people sell them cheap as f*ck. Put an ad on the internet in your local area and i guarentee within one week you will get 10 or more phone calls.

The $800 that kit will cost will make the 305 faster. You have to do the normal stroker clearancing on the block. And, you have to do the things to support more power, whether it's 305, 334 (it's 334 with .030" over 305 bore and 3.75" stroke - I don't care what enginekits.com says, do the math), or 350.

But, as has already been pointed out, could you find a 350 block and rebuild it for $800 worth of parts, including the 350? Of course you could. Much less, actually.

Powerhouse used to advertise "100 HP gain!" with their 334 kit. Big deal, increasing a 305 by 100 HP is simple enough - cam, exhaust, head work, easily there and plenty streetable. Doing those things to my 305 took a full second off of the 1/4 mile time. With the same changes, plus a 350 shortblock, another 1.3 seconds was taken off the 1/4 mile time.

By the way, not once was I asked, "Is that a 305?" while the 305 was still in there.

"Different" means either more expensive, or slower - usually both.

i have a friend with an early 80's elcamino, hes runnin a 3.75 strock 305(335) and its much quicker than a STOCK 350tpi, gets great mileage, but it really depends on what u want, something unique and great mileage? or a 350 like most of the ppl out there, did you beuild the stroker? im curious to how well it runs in a car lighter than an elcamino

I never built the 335. My plans have moved to building a 383 stroker.

I never even reached the potential of my 305 before it was miles ahead of any TPI car in this area. I basically got bored with it and didn't want to go through cutting up the car and swapping to an H/C/HSR 350. I went in this direction.....



Lid and catback it runs 8.2's at 86mph (1/8th mile of course). The Iroc is still around. I'm not saying one is better than the other so don't start a **** storm, just explaining the route I took.

I want to install this kit http://shop.enginekits.com/osb/itemdetails.cfm?ID=341 (from topicstarter) in my engine from 91` 305 chevy caprice

it will be engine swap for my V6 camaro

also i will install carburator, this project will be without ECM.

Some people say that if i'll build 305 on carb and with this kit then i'll receive huge detonation. Is it true?

thanks

P.S. Sorry for bad english i'm from Ukraine
