Re: Help deciding between 750 mech and vac on my 454
Total agree with you gentleman and that is exactly why I started my response with "If you really need the 750CFMs" . I have tuned and modded a 3310 till the cows come home using an AFR. Drilled and tapped the bleeds, idle feed restriction, throttle plates and the fuel blocks. Then milled the choke and finally put a screw in the secondary linkage. Performance picked up each time. I am the exception in needing more than 750cfm.
