Greetings!
I have a '75 with a 4 speed that is in ok condition. I have the opportunity to buy
a 78 with a 5 speed that has a blown motor and is in better shape.
Will the 75 motor work as a drop in or do I have to modify the wiring some?
If so, what modes should I do?
If there is anything I should be aware of, please let me know.
Thanks!
LaRue

if you try to drop the 75 motor in with its FI system then you will have to change wiring. But, just drop in the block/head from the 75 and use the intake/exhaust, the alternator, and the oil pressure sender from the 78. Should go in fine that way with a minimum of work.
