i have a 1992 camaro 3.1l it needs more power. i wanted to get some advice. i want to install a cam. it needs to be computer compatible. and anyone done theirs and what do u thing the power increase was.

 

260 grind from Crane Cams, lots of people here are running it

 

How big of a cam helps with these V6's?

I am an LT1 guy, and while engine work isn't new, my V6 knowledge is lacking.

I think I am going to change the water pump next week during spring break, and might want to change the cam then.

How big with stock heads? At what point does the vacuum get affected?

 

your pretty limited unless you can do some ecu tuning/prom programing. can you do that? check out www.summitracing.com they have lots of stuff.

 

A cam change alone isn't going to net you a whole lot unless you get a pretty lumpy cam, but as restrictive as the stock induction is and being that it's a noninterference motor you can get away with alot of duration. The limit is valve lift with the stock heads. I think you're limited to ~.450 lift unless you cut the guides down. You really need to consider getting the exhaust opened up before you look elsewhere, that's where you're going to find the most gains. Then induction, heads and cam.

 

260-2 grind is as big *** u want to go with tha stock ecm
call deltacams up 100 bucks for cam and lifters

 

Yeah I have a bunch of exhaust leaks and was looking at some pacesetterse + my old 3" exhaust from my other car before a cam. Even if the cam only adds 10 hp, thats $10 per HP, not a bad ratio comapred to some other mods....

 

Melling MTC-5 cam is about $100ish and is a decent cam, im happy w/ it.
