Has anyone seen or know anything about this crank from Powerhouse?

 

NO. That is the simple answer. The reason being is that everyone is too afraid to order it. Most of the comments you will get will have the words "just get a 350" in them. I would like to do this swap myself, but with the 670 pricetag on a college budget, i can't do it right now. I already have a 350 in a 70 chevelle which doesn't have to be smogged, so i want to try the 335 in my 88 firebird, with some sportsman II heads and an edelbrock intake with the lt1 cam and some comp cams magnum rockers. You are not alone in wanting to know more, but unfortunately this place is pretty one tracked, either work with the 305 you have, or get a 350 when it blows up. However there are a few on here who are likeminded, maybe they will pipe up.

 

Do a search for 383, and take a look at the work involved to drop that 400 crank in there. Take special note of rods hitting cams, oil pan rails, oil pans, cylinder bores... Thats why this place is one sided, why expend all that effort on a small bore block? Its not easy by any means. If it was, many more people would do it. You'll probably find that there really arent a whole bunch of 383's out there either, but quite a few 400's. Thats for the same reason.

 

I did a stroker 383 quite a few years back, had no problems out of it, but I had a good machine shop. I had to have my block machined to handle the larger crankshaft, if done properly, you will have no problems.

I thought about doing a stroker for my 305, but went with a 350 due to cost of the machine work involved. This is not just a bolt it in and go kinda thing. Also, when I called the guys and started asking questions about what heads and cam package would go well with it, they seemed VERY dis-interested in helping me out. That made me wonder about the support I would get if I bought their kit and had questions while putting it together.

just my .02

 

i am getting the 335 kit from powerhouse. i am ordering it in 2 months i cant let you know then.

 

excellent, keep us posted

thanks,

I have wrestled with the idea several times, and in fact I have been looking at it again lately. I have fantasized about the torqe a stroker would have.
I would rather have a 383 but then you would be pushing the limits all the way around. A 2brl TBI would have trouble feeding a healthy 383. I have recently bored out a trottle body to 48mm. When combined with my 65pph cop car injectors I think I could support close to 350hp at 20psi. My rear end would need beefing up(I have heard that the zexel torsion is good up to 350hp). I would guess that my chassis would also need re-enforcing. In other words I would need to bring the whole car up to the next level. On the other hand I could build a stout 335 and stay inside my present supposed parameters of = or < 350 HP.


Don't know yet what I'm going to do, but I need more cubes. I want to run my zz4 cam, so that might also be a deciding factor if I find out that it won't clear the crank.
Make no mistake, you will hear some crap about even considering doing a 335. And probably a 350 is more practical and I know it has more potential then a 335.

In the end, I'm going to do what I want to do regardless of what other people think is smart or practicle. I'm going to spend my money making me happy.

Any one else want to admit to considering a 335?
Jump in to this tread, don't be afraid, most of the world already thinks we are stupid for modding TBI.

 

There is not one good reason to stroke a 305. Unless you are aiming to get the least performance per dollar, in which case stroking a 305 would probably be a good start.

 

Pablo, if your saying that there is no logical reason to stroke a 305, your probably right. Maybe its emotional thing like right brain left brian, I don't know. I'm well aware that I would have 50 more HP if I would have done my mods to a 350 instead of a 305. Some of the things I do are just for fun.

Anyway I think the kit costs about $900, plus $100 to have my block bored and honed. So were are talking arround $1000 for a 10-1 compression 335 shortblock (some assembly required). I would throw my S/R torquers, ZZ4 cam, and Performer RPM manifold on. I'm guessing like 335 HP out of that combo. If I bought a 350 HO it would cost me about $2800 for the motor, shiping, and a vortec intake manifold. I would have about the same HP. Don't get me wrong, I think the 350 HO is a great crate motor, and a bargan at $2200.

If I could find a cheap LO5 I might just rebuild it and put my goodies on it. Don't know yet.

 

A set of Vortec heads with a ZZ3 cam, 10:1 compression, airgap intake, and 670 TBI wil yield closer to 400HP.

Scoggins Dickey sells the Vortec kit for about $900, that is heads, intake, and gaskets. They also sell the ZZ3 cam for about $190. I boutgh an LO5 shortblock for $200, $600 at the machine shop for the shortblock work.

Oh, and I don't know specifically about the 305, but when I built my 383, there was additional machine work required to allow for the larger crank.

Don't get me wrong, I think the 305 stroker kit is cool. I wish I had money to just build something because it was cool, and go through figuring out the little querks it has. If you do build it, I will be VERY interested in know the details behind what it took to get it going and what kind of power you were able to pull from your combo.

 

I researced the mods on project silver streak and I'm having second thoughts. They used S/R torquers, comp cams cam with 212 I, 218 E @ .444 lift, magnum 1.6 rockers, SLP headers and complete exhaust, and march pulleys. I would have though that those mods alone with the 10-1 compresion ratio would have produced 115HP with out a stroker crank and the resulting extra cubic inches. They started out with a 170HP 88 TBI motor and all they ended up with was 285HP with a custom TPI set up? I havn't seen the whole article so I don't know all the details.
Later, Dave

I dont know If they used a chassis dyno to test it. Maybe thats 115 RWHP. That wouldn't be so bad. Does any one know?

 

JokerRS, I have the magazine here in front of me with their last dyno results in it. It's the april 1999 issue. According to the article, they got 301.7hp @ 4700rpm, and 381 pounds of torque @ 3700rpm. I think the final set up was a Street & Performance speed density TPI set up, World S/R305 torquer heads, 1.5 roller tip rockers, etc.... I just wish I got to see the finished product, I was following that series closely, and would have loved to see some numbers (1/4 mile times, etc)> Does any one know if that car was ever given away? I can't find a follow up story anywhere. And BTW, (preparing to take the heat from the "why don't you just build up a 350" guys ) I do have a 335 rotating assembly in the garage ready to drop in my coupe, just have to button up some odds & ends, and she'll be ready to go. Yes, I know it's not a 350, but so what?? I wanted to do something a little different than everyone else, and if it dosen't work, I CAN use the 400 crank in a 350 block, and the heads can go in my convertible, so I won't have a complete waste of parts on my hands if it dosen't work out!!

:sillylol: Thanks I needed that!

 

Thanks for the info Derrick, 381 foot pounds of torque sounds impressive. I wounder if the HP is down alittle because the tpi was running out of breath. I have read that tpi doesn't do well above 4500 rpm. It seems like the HP peak should have been at a higher rpm with that cam and 1.6 rockers.

 

From a technical standpoint I'm not a fan of this bore/stroke combination. The 3.75" stroke requires a healthy volume of air/fuel to feed it at all times and mechanical efficiency will be inferior with the 3.736" bore over a 4" bore. There's just more surface area with a 4" bore and it's more efficient. From a performance standpoint (with an OHV configuration), small bore engines are not the way to go.

 

Ive got the 335 stroker kit in my 89 rs and it makes a pretty good engine...good enough to beat lt1 camaros sure it lacks in cubic inches but its also fun to tell people theyve just been beat by a 305

 

That's what I'm talking about 1989RS!! Where are you located at, and what engine combo are you running?

Got any numbers? how much was the total cost involved?

 

If you like being different then grab your doctor recommended crash helmet and hop onto the stroker 305 shortbus and enjoy the ride. Certainly not worth the price of admission but some people love learning things the hard way.

 

IT COST A TOTAL OF $ 940 (including shipping)To build the long block. Ive got the 670 holley tbi unit and stock lo3 heads they are killing the whole combo but none the less, it makes awesome torque till 4500. the top end really sucks, but im sprayin 125 hp worth of nitrous , which more than makes up for it Im running a holley street dominator single plane intake and a very mild cam.
it does really good off the line (1.83 sixty foot)no nitrous and it loses it all in the top, running 9.30 in the 1/8th,no nitrous yet,(I go back in two weeks) I should be more than capable to run 8.40 ... I hope!
p.s. I live in northwestern florida

 

10 min away from me....

 

interesting...

 

You're not still running the stock cam are you?!? If so... an LT1 or LT4 cam and some pick-a-part vortecs would really wake that motor up. I'd say sell the N2O and start part hunting... then you could be making that kinda power reliably (without a bottle heater) all day long

 

that is only about a 14.7. LT1 camaros are not that hard to beat tho......

 

True, sometimes it doesn't exactly pay (horsepower wise) to be different, but at least someone has tried it and we know what kind of results to expect. Trial and the occasional error are always better than bench racing in my book, although the errors do start to become quite expensive after a while

 

Dude-
In December you said you were getting the stroker kit for the 305 in two months.

Did you get it? What is the deal with it? Let us know.

Thanks,
S-D

 

got something for you guys if your interested, found this late last night go to www.high-performance-engines.com there is a tbi truck engine listed for 87-95 and smog legal in 50 states this is a 383----310 hp@4400 and 410#torq @3300----8.8 to 1 cr and gm 4 bolt mains--hyperutectic w/graphite coated rods and Scat 9000 nodular iron crank--- SR torker 76cc heads--1.94 int--1.60ex---.398 intake and .420ex------0.050----194'int---204'ex-----1 year limited warranty, just dont like the price though but oh well $3895.00 it says its compatible with stock computer , oh well who knows. i dont have that kind of money.just thought you guys should know.

 

A.K.A. the GM crate HT 383 Truck engine. Can be found at SDPC as well http://www.sdpc2000.com/cart.asp?act...tart&catid=120

But, if you ask me, the H.O. 350 is a much better deal at $2200 if you are thinking $$$ per hp wise. and has the potential to surpass the stock HT 383 with only a cam swap. That puts it at about $2600 with a nice cam and intake and with more hp and equal or greater torque than the $3800 HT 383. Not a bad deal.

 

I read in the March 2003 (page 16) issue of Chevy High Performance that they are coming out with a hopped up version of the 383HT. They're calling it the ZZ383. Listed at 425HP and 460lb-ft torque.
Probably get some pretty good coin for that, though it would be a blast in a Camaro.

Why not just build a motor

IMO, a lot of these high HP crates engines are rip offs

 

Like anything, there are pros and cons to each.

Here are three reasons why some people would buy instead of build.

* Some people don't have the know-how to build up a reliable bottom end.
* Some rely on GM's engineering experience to put together a proven combination of parts.
* Some have more money than time.

If you're set up to build, more power to you.

I don't know the cost of building that ZZ383 from constituent parts, but I bet starting from a scratch with a 350 and having all machine work done, would cost more than a few bucks and take quite a bit of time, also.

STOCK LT1s

 

I say F**k 305s,350s,383s and get a Ram jet 502, boost 20psi and go hunting for some ****!
