363 SBF with custom JE pistons. 10.6:1 fresh competition valve grind and new valve springs. 280# seat pressure, 700# open pressure.
The "scratches" are purely cosmetic. It happens when you pull the piston rings out of the cylinder to measure ring end gap.2nd pic, what's gong on in cylinder #5? Looks like some scratches or is that just the photo? Also tell me about the belt drive, looks nice!
Small tire stuff when I can. Around here it is mostly ET drags, no heads up stuff. I prefer the heads up small tire classes.What class are u running? U going to run supercharger?
