IM NEW TO ALL THIS FUEL INJECTION AND COMPUTER CRAP,I REALLY LIKE THE MPG I GET INMY 89 RS 305 AND I DONT WANT TO CHANGE THE COMPUTER AND OTHER THINGS IF I DONT HAVE TO.BUT I THINK IM GOING TO BUILD THE 335STROKER.ANY BODY DONE IT OR HAVE ANY ADVICE.IT WOULD BE APPRECIATED THANKS

MidnightTorker

I wanted to do a 335 too.. I think it would be cool.. the biggest problem is machine work... Just can't afford it. I say do it!

I saw a 32 ford with a blown 335 in it at a car show last year. Thing sounded mean..

Darn fuel .... 94 octane just went up yesturday to 2.45 here in buffalo. Not good.

NO A 3O5 STROKER POWERPLANT HAS A 305 KIT MAKES IT A 335.IT IS SUPPOSED TO BE A 115 HP INCREASE WITH A TBI

MidnightTorker

Yeah, I just commented on doing up a 383 instead . But then read yer post again and saw that you wanted the fuel mileage.

You might not get a good response from people.

Sometimes this board can persuade you from doing what you really want to do...

Just do it...

press the cap lock button before you start typing. as for the 335 stroker it's a great engine if you don't mind spending more time, money, and effort to produce less power than you can have with a 350.

Amen to everything ede said. Not sure why he didn't lock it, though, as these threads are numerous, and always turn into flame-fests.

The Board does have this nifty function as well.

If you think computers are crap, then you don't understand at all what contributed to the "115 HP increase" claimed by that stroker outfit. My LG4 was rated at 155 net flywheel HP, and is now producing approximately 245 HP at the wheels (based on accepted conversion factors - I've never had it dyno'd). It went from doing the (high altitude) 1/4 mile at 80 MPH with all the normal drag racer tweeks to 90 MPH as driven on the street. All without touching the crank, rods, pistons, or rings.

The problem with 305s isn't the stroke. The solution isn't adding more stroke.

RB83L69

That's exactly the crux of the biscuit here.

When you look at that ad, it makes it look like you take your 305, install this "kit" that increases the stroke, and just like that, you bolted in 115 HP. The reality is quite different.

Notice that the engine they used has different heads, a different cam, different exhaust, a different intake, etc. In other words, if they had taken a BONE STOCK 305, and done NOTHING else to it EXCEPT stroke it, the results would have been far less dramatic; or likewise, if they had taken a 305 and done all of those other things to it and compared the "kit" results to that, the gain would also have been FAR smaller.

Just a quick "smell test" should turn up something wrong with the ad's claim: you take this 305, that does 155 HP or 210 HP or whatever, depending on which specific model of 305 it is; that's something on the order of .5 to .7 HP per cubic inch. If you could add 115 HP by adding 29 cubes, that's right at 4 HP per cubic inch out of those other 29 cubes!!! Now, how can anyone make a claim with a straight face, that those extra 29 CID are SO SPECIAL somehow, that they each produce 6 or 8 times as much power as the cubes that are already there? The reality is, that out of that 115 HP, about 20 came from the kit; ALL THE REST came from all those other things, and were not produced by the "kit".

So let's look at the whole process you would go through, from start to finish: you take your "free" "paid for" 305 block (the cheapest part of the whole build-up); you buy this "kit", for $600 or whatever it is nowadays; you do all sorts of grinding on your block to graunch it in there, or more likely by far, you pay somebody to do it for you (let's make a WAG and just assign a price tag to that, let's say $200); and in the process you add 29 CID. Let's assume that you spend an appropriate amount of money on heads, cam, intake, exhaust, etc. and build a rompin' stompin' 334 as such things go, and you get 1 HP per cube. OK, that's 334 HP you've got now, and it cost you $800 to do it. Runs pretty good, eh?

Your alternative is to go to the junkyard and buy a 350 core. They're $50 most places for a worn-out core. You buy a "kit" for the 350 with a fresh crank, some rods, pistons, etc. like what's in the 334 kit, except that it costs less; and you put it together. Same machine work as the 334 such as boring, cleaning, etc. etc. except no grinding required, which means no $200 extra fee. Let's also assume that you get 1 HP per cube out of the 350 (which will have 355 CID after boring .030" - the same as the 334 kit). So, you've got a motor that cost you less money, puts out about 7% more power (355 HP vs 334 HP), and you don't have to grind on anything. And, don't forget, you didn't really have to buy a whole kit if you didn't want to, because you should have gotten a crank you could have turned and a set of rods in your core; so you could probably build the more powerful motor for even less. Even buying a whole 350 "kit", you're still several hundred dollars to the good and several HP too, compared to the 334.

So if you build the 334 and your brother builds the 350, you will spend more money than him, and when you race him, you will get pounded. Now how good does your 334 run?

That's what is meant when somebody says they're being "different".

This hobby is more about results per $$$$ than anything else. By that yardstick, the 334 doesn't pass muster. You spend more and get less by making that mistake, compared to the correct and logical way that both makes economic sense and produces better results.

Now if that 334 is really what you want to do, then go ahead and go for it. Nobody here can stop you. All we can do is warn you that you're making a mistake. Keep in mind, the rest of us have 2 things that we call people who spend more and people who go slower, though; we call them poor, and we call them losers. If that describes your goal in life, then the 334 idea is for you.

i like 305's alot. and i have seriously considered this kit. but after MUCH research, it really isn't worth it.

i have run as fast as 13.70 with a poor tune and my fastests mph was 100.5 mph in the 1/4. all off the shelf stuff, and i know it's got more in it. gas mileage really isn't all that great though.

if you want mileage and performance, i would go and do a head upgrade, and maybe a cam upgrade. headers/catback. and TUNE!

I gave some thought to the 334 (335) as well, for reasons of fuel economy. But after doing numerous searches and contacting some of the very few members who've done the swap the conclusion that I've arrived at, is that there are no phenomenal fuel economy gains to be found from doing the stroker mod alone.
Although it is possible to run some tall gears and still have respectable ETs.
Some of the most impressive fuel economy claims that I've seen were from LT1 or Miniram setups that were obviously tuned by someone who has some background.
But those guys were getting 30+ mpg and still running low 12s.
Very close to LS1 performance levels.

I'd suggest comitting several hrs to using the feature, and see what you can dig up.

I'm sorry I will never believe that a 12 sec car will get 30+ mpg maybe if you were going down a mountain in peak weather condition! I have a 05 Saturn 4 banger at best I get 25 mpg.

Anyway back to the subject brian89rs YES its true for the money 350's and other bigger engines make more power we've heard that over a million times. WE GOT IT! Now if your building a engine an want to be different an have something nobody else has an can make really good hp then I say build it!

Here are some links to people that have done the same thing!
http://www.cardomain.com/id/tunedport335
http://www.automotiveforums.com/t170164.html

Remember its your car you build what you want.

RB83L69

That's not the point.

The point is, they make more power for less money. Spend less, get more.

Look at it this way: when you go to the grocery store, and you're looking at a loaf of bread, and the tag says $1.19, do you go to the cashier and say "I really want to be different! I want you to take 5 slices out of this bag, and then I want to pay $1.29 for it. And don't try to talk me out of it by telling me that it's not sensible to do that, it's my money and I'll spend it like I want!"

That person would be "different", alright. Kind of like that one kid in high school that was "different" and nobody would go to the prom with them.

So why would anybody with 2 neurons that they could rub together, do this to themselves?

Listen to RB. His thoughts on the matter are just too damn funny but they are so so true. A 335 storker is not unique. It even sounds goofy. People will be more impressed with something else than a 305. Even people who know nothing about engines know that a 350 is "cooler" than a 305. Just start talking to random people about your car and listen to their repsonse when you tell them you have a 305. 9 out of 10 people will say "ah man you need a 350" or something along those lines. You can hear their dissapointment when they didn't expect you to say anything less than that magical '350' number. The same theory applies to clueless car show people as well.
Why do you think people lie about these cars all the time and try to pawn them off to some 16 year old as a 350. That same kid stumbles upon TGO and runs the casting numbers only to find out that his 350 charriot suddenly turned back into a pumkin with a 305 at midnight. He suddenly became mediocre with a low potential engine.

Still that's your opinion an if you want to be a bandwagon person just cause everybody else wants a 350 in their car that's fine. The guy is curious about a 335 an he wants to here from people that have them an I sent him some links with people that do. Judging by those links the people that own them seem pretty happy with them. I have seen magazine articles were they have made 350 to 400 hp with those engine and I'm sure this guy isn't trying to out run Vipers. He didn't say in his post that he wanted a budget build. I think a 335 is different an I've had 350, 406, 377, and 454 bored .125 now I have a 327 fuel injection that I'm trying to finish. If the he wants a 335 that can run 13's an get good mpg by all means build it. I won't think less of you if you do, its all in fun anyway!

Streetiron85

It is hard to believe, I'll have to agree.
I tried to find those links, but I couldn't.

DZ performance would be one site to look into if you're interested.
TexasLT1 is another member who's made such a claim.
It's possible you could contact them to get more info to back that up.

Magazine motors are often built under 3 conditions:

1) They are built to produce impressive numbers.
2) They are built to run on the dyno enough times to get said numbers.
3) They achieve said numbers sitting on a stand with no accessories.

Yes 335's are pretty fast but the fact is they have an impractical pricetag, which is in direct opposition to the entire point of smallblock chevy tuning. I think some really good advice has been given here. I also think there should be a sticky on this topic as it comes up quite frequently.

"Bandwagon" - that's good. And, opinion, not bad, either. Point is, how much gas can you buy with the money you don't spend on a 334 kit? Quite a bit. Make the 305 faster in other ways, get the same power, and same MPG w/o the money spent on the 334.

That's what the search feature is for.

Same thing has been done with 305's. As said above, on the dyno and not in an as-installed condition. Then they blow up.

Different and budget rarely belong in the same sentence, anyway. And, if budget isn't a consideration, why bring up MPG?

Okay, no need to beat a dead horse. If you're interested in a 335 (which is really a 334), do the search for the info.
