The 153 crank is probably twice as strong, if not stronger. the problem
with
running to much more rpms, is that the front of the block is very weak.
i
have arp main studs as well as head studs. should hold together pretty well.
i don't plan on twisting it any higher than 6000 rpm. the pistons are nylen
hypereutectic .030 over for a stock type 2.5
engine. the rods are crower 6 inch sportsman. comp ratio is 10.57 to 1.
cam
is custom grind by schneider racing. have head machined for 7/16 screw in
studs , and am using big block chevy roller rockers. have an adapter being
made to run a 4.3 chev pick up tbi unit, and am going to adapt a pick up
type computer into the car as well. should allow me to get a chip burned
for
better timing and fuel curves.
