i have a 67 f250 flat bed truck that the p.o. took the 360 that was in it and put a 300 out of a 91 in it. it was not complete when i got it, no tranny,no carb,no place for a fuel pump. is there a difference between the 91 and the 67 300? i got a carb at pull and save a single barrel brand new still in the box it was behind the seat of a truck. what manual transmission will bolt up to it? and what radiator? and what about the cylinder head the one that is on there now had the air tubes on it but they were cut off and crimped over. it is a project and it won't be a daily driver just a wood hauling truck.

 

The '91 300 was EFI while the '67 was a carb. Not sure of all the differences, but the '91 would've had an in-tank fuel pump so it probably doesn't have a place for the mechanical pump. It also would've had a very different intake manifold that would not take a carb. It also probably had a sepentine belt system rather than V-belts.

As far as what manual trans will bolt to it, I'd think pretty much anything from any year, as long as the bellhousing fits the small block engines (300, 302 or 351W).
