A buddy of mine has a parts truck for sale. wondering on parts compatibility on the intake,carb and possibly the heads on a 351c fitting on my 351m? thanks!

 

2v heads will interchange. 351c never offered in a truck. Intake is different, 351c is narrower.

 

I was wondering cause he had a 4 barrel holley on his and i have a junked 2 barrel motorkraft

 

If you want the 4v Holley you need to get a 4v intake particular to the 351M/400. Or get the 'C' intake/carb and get intake spacers.

 

My my older brother had a late 70s truck with a 351 Cleveland in it hate to burst your bubble that was original motor F-100

 

timing chain fit but probably need to be change, oil pump, distributor, heads, pulley, cam also fit but i wouldn't change old part from a 71 to 74 351c to swap on a 75 to 79 351m or 1971 to 1979 400. The only thing that will change is the 4v heads in certain application if its a 351c with 4v. If its a 351c 2v its the same(almost) heads as 351m or 400.
The 4v intake from the 351c need spacer to fit the 400 and it's just as much expensive as a 4v 351m/400 intake. just my 02.

Can you get the block ID from the 351c ? locate underneath the passenger exhaust manifold.

 

Did your brother live in Australia, New Zealand, or South Africa? If not, did he import his truck from one of those countries? Those are the only countries where Aussie assembled RHD F-Series trucks received Aussie built (Geelong Foundry) 302C/351C engines. If he didn't buy a RHD import, then it wasn't original to the truck OR he was believing the old car salesman trick from the 1970s. Back in 1975, Ford had discontinued the 351C but brought out the 351M and to keep up the sales mystique, they would call the engine a Cleveland.

 

What he said.
