kind of an oddball question.......i know you have to machine the crank/ use an adapter to use the 727 on an "earlier" engine, is it the same deal in this case? my neighbor is in the middle of doing it, but i'm thinking it's more than just a "bolt on" deal. all and any feedback is appreciated. -- Colin Hillyard Oakbank, Manitoba, Canada 68 390 AMX - sold 69 JAV SST - parts car 69 BBO AMX - on the project pad, 70 390 AMX - ram air - golden lime shadow mask - auto 70 390 AMX - ram air - bittersweet shadow mask - 4speed
