1970 F100 engine swap

Different engine perches and bell housing bolt pattern, so you will need to swap more than just the engine. But it's a common enough upgrade, you should be able to find aftermarket parts/kits to do the swap, or if you live somewhere that still has older cars and trucks in the salvage yards find the 390 engine perch there.

The 390 was an engine option for your truck so you can do this swap with all factory parts.

Thanks. Do you think the transmission hump is any bigger on an original automatic car as opposed to an original 3 speed manual car? i read something about low and high hump. Thanks, John

If you need the bigger hump you may be able to swap from another truck or buy aftermarket.
