hello all, first time user. I just bought 1970 f100 w/ a dead 302 and a good 3 spd.tranny I've got a line one a 85 elec.feed back[junk] carbed 302 w/ aod trans I thinking of puting in . I will be replacing the intake & carb with the old style orignal hope it works!!
Are you swapping the AOD in as well? You might have to settle with swapping the carb for the time being. I think the intake bolts patterns are different, but don't take that as 100% correct since it has been a while since I ahave played with one. However, since the two 302's have different harmonic balancer weights, 70 28oz & 85 50oz you wont be able to swap the flywheel to the new engine. So if you are a die hard for the manual you will need to rebuild the '70 302 while you swap in the other drivetrain.
yes i'm going to use the aod. what about the axle ? will I have to change them out . the 70 has 9" the 85 is unknown. I going to use a floor shifter out of a bronco 2
