Quote: If these #s are correct these puppies are in W8-9 territory. I better wait before I bolt the Indys on the new R3 shortblock I have on the stand right now!!
Even though they are in W9 territory they are a 59° Head ,well they pull the same RPMs as a 48° block?
Just make it bigger, like 440-470 ci and you don't have to worry about the RPMs. It will make a ton of torque, more horsepower and operate in the same RPM range.
