Engine Upgrade
Looking at upgrading my motor using the following specs on the AFR web page:
AFR 195cc street heads
AFR Flow Power intake manifold
Comp Cams Hydraulic Roller Cam #12-433-8
1 3/4” Headers
I was wondering:
1. If this will result in a significant power increase from what I have now (see signature)
2. What make of 1 3/4" headers would work best with my Corvette and these heads. I have power steering and a TH350.

Spend about $40 on a desktop dyno program. You can play with a variety of setups to get what you want, then buy the stuff that you designed. I did this with my 383 and it dyno'd exactly like the program predicted. The motor is awesome; now for the tranny. Good luck

The reason I like this setup is that AFR has an actual dyno graph for it on their web site. C3 Stroker's numbers seem to be about the same as AFR's.

I'm running a close combo on my 383, except with a hydraulic .541/.544 cam. AFR 195s, port matched Victor Jr. and close to 500fwhp and 500+ should be easy for you with the AFRs. Hooker Super Comp headers should work fine, but they hang kinda low..so if your car is lowered...just watch out.

Redshark,
Nice engine bay! Speaking of headers hanging low, my left header got a bit crushed when I was blinded by sunlight, missed a driveway and climbed a curb on one side. I only have about 3 1/2" of clearance with my current headers.
