Cam help

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:
