yes,just when I thought I was understanding. ok both stroke and rod length can effect port velocity.
can you tell me what rod length would work best in a sb with 4" stroke and using an indy 360-1 head with 2.87 [Email]csa@13.5:1[/Email] compression?



Your basically stuck with certain length rods.. you
need to fill the space from the crank to the piston
and based on stroke and deck height your in the 6.125
length with some minor length changes due to pin
height in the piston
