porting
Has anyone here run stock edlebrok alumn. heads on a 428, then gone back and had them ported/polished?
was it worth it?
Noticable gains or losses?
Would you do it again?
what are some of the specifics? (cam, compression, etc.)
thanks for the info.
Trying to find a way to up the net horsepower a little.
would like to hit 500 to 550 at the flywheel on pump gas.
