From my experience on these motor swap/improvement would be a 351 of some version - far easier and less expensive with a good improvement.  |
Greetings, lizziemeister!
Not only will he need to change from timing gears to timing chain and sprockets, he will also need to change the camshaft itself, since the original 478 camshaft will now be rotating CW instead of CCW. There is a difference between cam grinds on CW and CCW rotating camshafts.
