I'd like to hear from other C4 owners on what mods you've done to your car? I have a 1996 LT4 that I'd like to squeeze another 100HP out of.

What is your budget?

The first thing I did to mine was long tube headers.Followed by 4.10 gears.Then I did a cam and the motor went south in a hurry(not the cams fault the thrust bearing on the crank was shot and I didn't realize it at the time).Then it became 383 with cam/afr heads/EWP/msd ignition/dyno tune.

If I had it to do over I would go with long tube headers/maybe a hotcam/and a tune.May not be 100hp but look up JONECAP and what his was running with not much more.

It all comes back to what your budget is.

Thanks for the reply. I planned on doing the exhaust first, but wasn't sure about swapping out the cam. I'll like do a similar setup to what you have. Want to spend a total no more than $3k
