I'm swapping out the 351m out of my f-250 "79" Ford for a 400m out of a 77 any complications you guys can see a Head of time this is my first time tooling on my 79. swapping out the stock carburetor for an Edelbrock 1406 600cmf plus adding a 400 4brr intake..

 

I would think it would bolt right up since the 351M/400 are in the same engine family

 

Remove the engine and note the steps you take , then install the new engine by reversing your steps , easy bolt in .

 

thank you guys so much for the info. any concerns about the carburetor, engine, and intake that i'm using. talk to an old friend today he said Edelbrock are really hard to tune. Thoughts?

 

There is no such thing as a 400M...only a 351m. The 400 is simply a 400.

 

I'm running a 1406 on my 460. It's a very easy carburetor to tune. If you have any trouble, try watching these videos:

Edelbrock.com - Tech Center - Carburetor Installation and Tech Videos

 

I have a holley 600 on a 302, a 460 being built now ,going with eldebrock on the new 460

 

I have a new question.. I forgot to unlock my hubs and ran all summer with them locked in and now my 4 wheel drive doesn't work so my question is. Is it the hubs or do I need to take it to the shop??

 

Nope...just unlock them.

4WD not working is another matter you need to address.

 

Ok thank you
