318 Senior Project Build

Thanks for the advice I might have to start considering it now looking at everything I'd have to do to my 318.
If I were to do the switch would a 5.9 still bolt up to a a904 trans? I just had the transmission rebuilt a little over a year ago so I'm trying to keep that in the car as much as I would love to have a 4 speed.

No problem using your 904. If the engine you get doesn't have the correct flexplate (comes on later year magnums) then the one I mentioned in the other post would work fine.

You mentioned that you've already got a carb and intake, what are they? If the intake is good there is a way to run it on a magnum even though the bolt pattern is different.
