3500 max hp

[gar70614]

sorry for the "newb" question but i havent found a difinetive awnser searching. wat is the maxx horse that stock 3500 internals could handle. i figure forged rods and crank would hold up well but pistions and timing chain.... i was thinkin boost wise i know theres a lot of exeptions and such with awsome tunes and wat not but like 300hp? more? less? any imput would be greatly appreciated. thanx

The 3400 has made over 300 WHP with turbo and stock everything, so the 3500 can do that at least I'm sure without breaking.

SuperDave put down 270 something WHP N/A so that's over 300 crank...

im sure it can go well over the 400 hp threshold when built right. forged 3500 crank seems to be a pretty stout piece and the bottom end is cross-bolted, so, factory girdled. not sure about the rods and pistons.

sweet thts awsome to hear. guess ill have to just boost and see wat it takes to break lol thanx guys

A semi-local (200mi away) was able to get 340hp N/A with a highly modified 3.4/3400 with custom ITB's and open headers, but the block split down the valley running in a Midget car and 6500 RPM limit. He bought a 3500 block from me and learned about the 3500 heads at the same time, so I would love to see what the future brings on that.

Please read: Speed costs - how fast you wanna go?

There is a guy here who broke into 10's with an X car, and stretched the Gen 1 (Gen2) mains with 450hp.

[Superdave]

there are several gen3's over 400 HP.. i'm at around 320 crank HP

i was curious as to what anyone thinks my power will be at once i get this thing tuned good. dave, i know you'll probably have a pretty good idea since you've been working with me on the tuning.

sorry to hijack the thread but I have to ask... was this a 3.4 dohc or a 3400? 2 different engines. the dohc is a known pig but the 3400, well it has a better reputation even with gasket issues. I've been running around asking about the 3400sfi and cracking the block and so far all comments have been positive. if you're saying otherwise then I may have to rethink my planned mods. please let me know.thanks

again sorry for hijkacking the thread.

Neither. 3.4L RWD Iron head motor, with flat tappet cam. Found in camaros. It is a Gen1 V6, the 3400 is gen 3. The one that split there was the 3.4 iron head block, with 3400 aluminum heads bolted on to it for more power... 3400 has crossbolted mains and much more modern design.

[ForcedFirebird]

Yup. Camaro block. The valley design changed when the motors went roller and there is a lot more meat between the head decks. The guy actually bought a 3500 block from me to build up, and was actually impressed with the newer 3500 head design, so it will probably end up being a full 3500

I just did a rough tune on a 3500 with a 1617 cam, P&P'd top end running 3500 "header" manifolds. There was a power outage at the dyno this weekend so we didn't get to put it on the rollers though. I bet it's around 260 WHP with a nice flat torque curve.

It's simply amazing how the 3500 reacts to a good cam and a good intake/exhaust setup.

whats that john lingenfelter quote? bolt on a great set of heads....

Yep.. lol


Another 3500 Jbody swap, bone stock engine using 2.8 log manifolds with i think just 2.25" exhaust and a cone filter running on a tune for a 3400 with 00+ injectors and FPR put down like 205 WHP after we bumped up the fuel pressure to 65 lbs.

Everyone was down on power last Friday, i dyno'd about 20 HP less than last year on the same exact tune. The other guys were all down from the years before as well.

It was hot and humid..
