Hi, I have a 1992 silverado with a throttle body 350. All I have done to it is an aftermarket edelbrock intake manifold and I have removed the catalytic converter and installed a flowmaster muffler. I was wondering if any of you guys have modified engines like this and if so what would you suggest doing? I was thinking about camming it and possibly installing new heads along with headers. Any suggestions on what I should buy or what cam and heads are best for this engine? Thanks!

I had a 97 Sierra, with the 5.7L (not exactly the same as yours, but close). It REALLY woke up with a CAI and Flowmaster cat-back system. It was a lot faster, and I upped the fuel economy 2 MPG. That was all I ever did to it- it had close to 300,000 miles on it, so I traded it in for my current ride.
