Ported 853's I have a fully built 347 with a Trex cam, Super Victor, 850 proform DP. I wanted to know how much horsepower I'm leaving on the table with a set of ported 853s, rather than a set of AFR's.. I have this in a Sand Drag truck btw with a Turbo 350 and a 4000 stall converter. Just wanted to hear your guys opinions Thanks!
