Reply to "Boss 302 Motors"

When swapping engines in a 'Goose, its not engine length that causes trouble, its the fact that the 289/302 smallblock in the 'Goose came with machined bosses on the top of the right side intake manifold to provide a place for the jackshaft to bolt down. Sure, Boss heads on a 302 will fit great, but then you're faced with building up those mounting bosses- or finding another way of powering the A/C and alternator that normally run off the jackshaft. The 302 intake will not fit the radically different Boss heads and since Boss 302s were never supplied for 'Gooses, there is no commercial intake for this combination. The adaption to Boss heads in a 'Goose has been done (Steve Liebenow's blue '69 has one) but frankly, its not worth the trouble. FWIW, the neatest, most elegant swap I've yet seen in a 'Goose is a late 5.0 EFI-equipped Mustang engine with the 'Goose-specific block fittings swapped over. Of the several running around So-Cal, reportedly the only problem comes from adapting the jackshaft (again!) to the EFI intake and a minor interference at the edge of the access door- corrected with a small grinder.
