Any idea if the 300 would bolt up to my 3 speed? its a 1954 f100. not sure what the 300 is out of. how tough would this swap be

 

There's a lot of great options for transmissions that match the 300. C4, C6, AOD, and mine has the SRO-RUG. It just seems to me that you would lose some of the benefits of the 300 by mating it to your old sideloader. I want to say it takes a non-standard and expensive bellhousing to get that done, but i'm not sure. I can't remember where I saw that.

I'm in the process of putting a 300 in my 54. It's not a bolt in swap, but it's not too complicated either. You'll need an aftermarket crossmember, about $120. And possibly new motor mounts, but it depends on what year your 300 is. Is it EFI or carb'd? (EFI wasn't introduced until '87)

Head over to this forum and do some searching...I think you'll get your questions answered.

Yeah. I would do a ZF 5 speed with a 300...

 

The 300 has the same bell housing bolt pattern as the small block Ford. Find an adapter bell housing to go from the small block bolt pattern to the three speed bolt pattern. You will have to do some looking since these are out of production, but they are out there.

 

Since you already have the clutch pedal and linkage I would suggest that you loose the 3 speed and install a 5 speed . Then you get the advantage of Overdrive .
