    If Im converting to carb, some of the write ups say an HEI distributor and some just say a distributor from an 85 5.0 carbureted. Trying to figure out which one I need. Either way, are both used with a Duraspark II type ignition box?

    thanks

    You could also go with a billet unit with vaccum advance too but thats up to you. I know you can use a HEI style setup which is made for Ford but that its big and ugly! LOL

    Which is which though? It said I need a duraspark box but I need the distributor that has the vacuum advance also? Basically a stock replacement for say an 85 5.0 carbureted?

    thanks

    HEI is like a GM dizzy. The coil, ignition module are in the unit. The Duraspark keeps the coil and ignition module external. Yes a stock replacement for an 85 5.0 HO engine will work.

    ok so I'd get one of those and it would tie in with one of these?

    also would this be a good lower intake to go with? Need something square bore instead of spread bore, all the carbs Ive found have been square bore

    [​IMG]

    ***per website***

    Cobra 4-bbl High-Rise Dual-Plane Intake Manifold for Ford 260, 289, 289 HIPO, or 302 V8 engine.

    This is the "large letter style" Cobra aluminum intake originally used on 1966 Shelby Mustangs. It is a good mid to upper RPM manifold.

    For use with any carburetor with a Holley 4-bbl flange.

    RPM range: 2,500 - 6,000


    thanks :nice:

    i run a holley 750 hp no choke double pumper. the one you listed is like the one you showed a pic of the one i gave you the # for is barely a little taller but lets air under the plenum and runners like a victor jr. its the rpm range you want w/o the vapor lock the other may cause.

    Would a Holley 650cfm be too small/large for my combo?

    weld on drop sump, filter befor pump to keep trash out of pump, holley blue pump, 1/2" fuel line, regulator set at 10 psi, and 750 hp. this is what worked best for me becuase of my situation. a red pump back by your tank, and taking your in tank pump out and put a peice of metal line in place of it will work just fine if u dont want to go through all i have had to. My car kept running out from under the fuel at launch so i did the sump, the juice is why i did the rest

    whats your email i dont know how to attach the pics here

    so you took out your in tank pump and just ran a line to the bottom of the tank and then up to the externally mounted pump?
