Chris, you mentioned raising the rev limiter to 7500rpm. When doing an engine build, how do you determine what is a safe rpm number for redline? What factors play into this determination? I know a number of tuners raise the rev limiter on stock cars when you buy their flash. Is that safe?
1 rod angle. 2 rods and rod bolts 3 weight of valve train. I run 8000 rpm redline but shift as soon as my torque peak is ideal for the next gear

Pistons and sleeves looked good wen they came out, and 4 out of 6 rods seemed to have started bending. I'll be keeping the stock oil pump and head studs. Raising the compression would be nice, but I wanted to keep this build pretty basic.. its usually the basic setups that end up doing the best . Thanks for the compliment on the head work, I'm really happy with the guys work as well. Yes, I changed to single groove keepers.
Happy Wednesday gentlemen!

Makes no difference. It is piston speed. the sharper the rod angle the fast the piston accelerates in the bore. At a given speed the piston material will hit its pasty temp and stick to the sleeve. That right there is game end. No oil can save you.

Your WHP would be similar to mine,not exactly because you have RWD and another variables.
