a 6" rod will set the wrist pin higher in the piston so you can use a shorter piston. some say you can rev it higher witha 6" rod because there is less reciprocating mass and others say its bad to use a short lightweight piston becasue detonation will destroy it easier since there is less material on the top.
what shop is going to do machine work for $300?
mine was $1800 for align honing and boring the mains and bores. the bores were done with a torque plate and i have splayed mains so that might be why its higher, but i thought even a budget would be more then $300 in macinhe work.
