302 swap questions October 22, 2006, 05:01:49 AM i guess first question is, are there any adaptor that allow the efi-style throttle linkage to work with a carb, or am I gonna need to retro-fit a throttle cable from and older Fox?Secondly, what size carb would be a good starting point for a 5.0SO with E7's, stock Stang headers and aluminum 4bbl intake?And last, would it be alright to use a fuel pressure regulator to drop the pressure down, or should i drop the tank and get a new sump and sender? FWIW, i'm eventually going to use an efi 5.8which brings me to:I know I was originally going to go with a 5.8, but that engine will need a complete rebuild, whereas the 5.0 bottom end is all good.I figure to swap on the E7 heads, stang headers, and depending on the cam specs of the monster I have, maybe use it, but the box says only for mass-air 5.0ho/5.8 engines, and the lift is quite high, IIRC around .480...so i'm betting it won't work with flattop pistons..Anyway, I'm gonna run this setup for the winter/spring, and in the meantime, try to put some money into the 351w.

302 swap questions Reply #1 – October 22, 2006, 02:49:49 PM I suspect you're going to have to find a earlier type linkage, possibly the CFI setup would work with a carb...As for the carb just remember this, the HI-PO 271hp 289s used a 470cfm carb. So anything above 600 is just overkill and will probably cause low speed bog/stumble especially in cold weather...The FP decision is yours, but I've always thought it may be possible to connect the supply line directly to the return with a "T", then use a regulator to get the 7lb or so the carb would need... This would eleminate the need to find a earlier type tank/pickup and a mechanical pump on the engine would be unnecessary... Quote Selected
