Corzette Posted July 7, 2003 Share Posted July 7, 2003 Guys I just wanted to ask your opinions on this. I want to buy the Proform main body for the 750 Holley DP. http://store.summitracing.com/partdetail.asp?part=PRO%2D67100C Is this a valid investment? Also, the link below to save me from buying a million different jets, would this be a good option? Anybody got any input on the quality etc? Im thinking about getting both of these upgrades...please advise. http://store.summitracing.com/partdetail.asp?part=HLY%2D55001HOL Exhaust is done and man it sounds sweet! Gonna Dyno in a couple of weeks! Quote Link to comment Share on other sites More sharing options...
Guest Phil1934 Posted July 7, 2003 Share Posted July 7, 2003 Glitter. Do you really need the few extra CFM from no choke? And $80 will buy a lot of jets. Holleys are close but a little rich. 2-4 sizes less should do it. And the weather and altitude change have to be large to justify swapping jets so once you get it, you're done.
