440
.030 with torque plates
trw six pack replacement pistons
rpm I beam rods with 7/16 arp bolts
arp main bolts
440 source heads- not ported yet.
Hv oil pump with deep pan 3/8 pickup.

So my question is, where would you guys draw the line for limiting horsepower and rpm, head porting, cam size etc. If it was yours how would you build it?
