measure the length of your catalytic converter.. then get a test pipe made. you probably won't see much of a gain anyways unless you were going turbo, squeezing, or heavily built NA.

 

it has all new internals
itr cams
itr crank
crolwer h rods
crolwer pistons
je piston sleves
crolwer valve spirngs,retainers and keepers
