That's right. I'd like to get these numbers or better with stock heads, crank and rods. Possible? I Have a D4 block that will be cleaned up, lined, bored, honed and decked. From what I've learned reading many threads the crank and truck rods can handle 500 with a good balance and assembly. The only reason I mention them is because I have no desire to go any combination of stroker so PLEASE don't even bring it up. I also don't want to spend money on a RETRO anything or increasing valve sizes. The stock heads will be ported and get a good valve job. Also I have some good roller tip 1.6 rockers I'll be using and a Eddy performer intake. (not an rpm. I know, but it was a freebie) Can someone fill in the blanks for a good flat tappet cam, carb and piston. Any help is greatly appreciated.
