A question about rod length, piston speed.
I'm running a 6.160 rod. the stock length is 5.94. The stroke is 3.98.
Will the longer rod.
A= make more lower end torque?
B= make more power in the higher rpm ranges?
C= not make a hill of beans difference?
This is for a 4 cylinder car with an automatic (2600 pounds), I need all the torque I can get.
