http://i355.photobucket.com/albums/r461/FriedDonuts/port%20mold_zpsbotjhqo8.jpg Made some port molds earlier this winter of my performer R.P.M. port and Bubby 440'S new trick flow 240 port. Mine have been mildly ported and are 220c.c. vs. I think 215 c.c. stock.Looks like most of the increased area is in an improved bowl area. Minimum cross section at the pinch is the same.Edelbrock on top t.f. on bottom.
