Combo opinions...

Here's the basics of what I did with mine...
block bored .04 over
Keith Black "167 - 040" pistons
302 heads with 1.88 Int/1.6 exh stock 1.5 rockers
Comp Cam XE275HL
Edelbrock 7576 Performer RPM Air Gap Intake
Edelbrock 1406 600 cfm carb
TTI step headers
Electronic ignition w/ orange box

I don't recall how much was put in the head money wise. The 1.88/1.6 were already in it when I got it and I port matched them myself. I think the thing that made the biggest difference that I did was the kb pistons. I don't know what my hp numbers are, but I would say conservatively 300, hopefully 400, but realistically, somewhere in the middle.
