keep that a whack a mustang t5 in it ...
get the v6 one with the truck like 1st and a 0.73 Overdrive
or the AX aisin warner that they used in the dodge trucks a bellhousing from 318 to the aisin warner exists makes it easier than the t5

you can then keep your rear end for sprightly acceleration but have an overdrive that MIGHT allow a little more than 55 MP on the motorway
gotta be better than a 3 speed
you'd kick the ass of any split window VW
i come here to plant seeds, that will empty your wallet
