I have a 1969 large journal 327. Basically stock rebuilt bottom end with forged pistons w/ pressed wrist pins and ARP rod bolts. I plan on using some ported and polished 882 castings cut for bigger valves (2.02 Intake,1.60 exhaust) and screw in rocker studs. My compression ratio should be 8.25 to 1.
I want to run 12 lbs of boost, but I was told that pressed on wrist pins will break and stock rods will bend or break. It was said that iron castings do not like a lot compression and that I needed a floating style wrist pin and h-beam rods. I just want to know if this has merit or if this person was just trying to sell me somthing.... I have some pics ask if you want to see
