so in stead of getting a new motor my granpa is gonna help me rebuild my 302
now heres my question i have a electronic fuel pump not sure of the specs on it but i belivev it would be the same fuel pump they put in crown vics (or stangs) from 86 to 93. would i be able to use the electronic fuel pump or do i have to use a mechincal fuel pump also if i can get a 351W (a 1973 351W to be exact) will it bolt directly to a AOD tranny or will i need a different bellhousing
ps the carb going on the 302 is a 650 holley

If you are going to go with a carb on either engine you need to get a fuel pump that only puts out about 6 pounds of pressure. The stock pump for EFI puts out about 30-35 pounds and requires a return line. That much pressure is too high for the carb. You need either an electric fuel pump for a carb or you need to get a fuel pump eccentric and timing cover that accomodates a mechanical fuel pump.

Check out this site for info on converting to a carb.

ive got the return line with the fuel pump but i would like to keep as much of the engine bay clean (so its not so cramped) and if it doesn't have to go in the engine bay then it won't
but thx for lettin me know

what kind of timing cover will need and what kind of intake will i need to get (would it be the same as any 302motor)

If you are going to a carb any carb intake will work. Which intake depends on how you are building the engine, high end HP or street torque. Which cam you get also has an affect on choosing an intake.

The different timing cover is only needed if you go with a mechanical fuel pump. If you are going to go with a 6 psi electric fuel pump then you don't need to worry about it. You don't need a return line with the low psi pump and a carb either.

I just realized your car is an '81 and is already a carb'd engine, unless you are going to build a different engine. You should already have a mechanical fuel pump or an adequate elctric fuel pump. I would have thought your car would have come with a mechanical fuel pump already?
