    EFI for my 65 Barracuda -- 2bbl or 4bbl

    I’ve done both Holley and Fitech. Personally I like the Holley better. I like the Holley tuning program better. I’d go 4 bbl if you are planning to make any upgrades later. If not the 2 bbl will suffice. Keep a little $$ aside for some incidentals. Holleys are fussy about RF interference and...

RIGHER is always safer especially if you are running stock cast pistons. Detonation will kill the motor quick...

If it revs up/smooths out/ keeps running you either have a vacuum leak ( which can clear up when hot) or the choke needs to be adjusted. How much tension is on the choke plate when cold. You should be...
