Dose any one anything about GMPP cam or Crane H260-2. Whats the peck power of the cam. Thanks guys.
"Good idle, daily usage and off road, towing, economy, also mild turbocharged, 2200-3000 cruise RPM, 8.0 to 9.5 compression ratio advised. Basic RPM 1500-4500"
No clue where it would peak. Depending on what you already have done, you might want to consider other mods than a cam. There have been quite a few stock turbo/stock cam cars that have made a lot more power than stock....
Ok thanks I got the car from my friend thats the cam he put in there. witha t3/t4 turbo .57 trim. 3400 hybrid 65mm tb with 3500 intake. i really dont under stand why he put that cam in there. I dont want to over rev the car if its not making power past 5,000rpms. What kinda power i could see with this cam. I have the boost set at 11psi.
some back ground on the car. My friend got the car back in high school i helped it from a 3.1 auto to 3.1 5 speed turbo and people get older they start to grow up. He rebuild the motor with new pistons and that cam with 3400 heads with ls6 springs ect.. that i listed at the top. he built the car it ran then it got tuned then after getting tuned it just sat. so i wanted to do stuff the right way.

so 3400 heads will fit on a tgp 3.1 with no mods.?
yes u can do a top end swap with 3400 heads and intake

WOW really,, what type of performance is expected ?
20-30hp with a tune. The top end will be much revised which will allow the power band to stay in longer.
3400 top swap requires custom length pushrods.

there's the oops well im not going there fur sure
thanks guys
NOTE* pushrods are not connecting rods. Pushrods are cheap and easy to retain.
I don't know if the later heads allow for this but cant you just use the adjustable 2.8 rocker studs to make up for the length and just grind a little bit of the guide.
The 3400 used roller rockers and 2.8 used stamped steel. So no you cant use 2.8 rockers on a 3400 head.
custom length pushrods = not that bad.... if your going to dish out the cash for all the stuff for the top swap, custom pushrods are chump change... http://wot-tech.com/shop/all/custom-length-pushrods/prod_78.html
If you know how to measure and follow directions, you can save A LOT of cash by going to summit, jegs, or some other long time reputable performance store. wot is like going to the liquor store for that dollar store candy. You're paying top dollar when you can get the same thing cheaper somewhere else!
Just bought this cam kit here

(flatlander racing has it for 275$,summit will do $274-I got it for $286 shipped!)
It will be a couple months before the engine is in and going though so can't give much of a review of it.
It's a 110lsa instead of 112,but the price was in my budget and power isn't my main concern.
I'm going back and forth trying to decide if I want to put the engine on a dyno before installation.
Not alot of point in it if i'm not going to be tuning it while it's on there,and I don't want to tune it myself.
if you can afford the dyno time, do it, it will help alot with perfecting the performance of the engine
Well,I have a slight relationship with a couple machine shops that have engine dynos.
Slight as in I could I could use them for some machine work and get them to throw it on the dyno for a couple quick runs.
I wouldn't throw down the kind of money it costs for this particular engine.
If I could afford the time it would be nice though.
I have a 95 3.4 complete engine,2.8 fiero complete engine,3.1 complete engine etc..
I would love to tune the intakes swapping different parts etc to find the best fit.
On my buddies engine (he worked at one of the shops) they put it on the dyno,they could read it like a book. Could tell when the intake was running out of air,the carb,etc..
Kept swapping parts till they ended up with his final number (over 500hp on n/a 377 before 200 shot,built for 400shot,crzy engine-in a little blazer!)
I've decided not to dyno the engine anyway,no machine work needs done. The buddy mentioned above is going to do the seats and cam bearings at his house.
Has nobody used the cam I mentioned above or one with similar specs?
I used to have that cam. Its a good all around cam as it has 0 degree overlap but for boost its not optimal. It will lag a turbo a little more than if you had a true boost cam.

I love de-strokeing the 400 block. Had lots of success with a 327 crank and a super long rod. Makes 348 CID... :icon_twisted:
Yeah,and you gotta love spinning to 8 grand and above :)
noisy gear drive... nice!
