Manual trans is out of the question unless someone wants to donate a complete set up. I think with this low powerd motor the early dakota 5spd should fit and work best. The a-500 has a higher OD ratio and the trucks with them don't seem to get much if any worse miledge than the 5spds, but I would prefer the 5 spd personaly they are more fun to drive.

The original 273 heads are not hardened seats. The 302 has more swirl and velocity in it also. I am torn between the 302 and MAG right now.

I am in the process of moveing right now so I have not started yet, just gives me more time to plan. Keep the ideas flowing.
