I have a chance to get a 351M motor cheap (read free). I'm told it is out of a 79 F150 and is a real low horsepower motor. I am familiar with 351 C and W but am clueless on the M version. It would be a project that would sit in my garage until I have the money to do something with it and put it in my 65 fastback. Is it worth grabbing? Can it be put in a 65 or is a boat anchor?

Thanks for your help

Boat anchor seems to be the general consensus

There was a 351M and a 400M, they both have big block style bolt batterns, are very heavy, and were made for trucks. Not much use in a mustang

If itís free why not? Its not as bad as some people think. Put a 400 crank in there and use some 351C heads. Not as simple as it sounds thought. These engines are similar to 351C's and if I am not mistaken there lighter than big blocks. Power can be made with these engines. But lack of information, aftermarket parts, no proven combinations because no one really builds these engines up for performance. Called a boat anchor now but who knows? Simpler to stick with proven engines

Not an abundance of performance parts available for the 351M-400 engines. I would not even bother unless you want it for stock rebuilder.

They have oddball motormounts so there is no available mounts to put in the stang.Also as stated all but a very few come with a big block bellhousing which may not even fit in a 65.Its just not worth the hassle even if its free by the time you fabricate everything to fit in in your 65 (assuming it will even fit) you could have bought a decent rebuilder engine that will fit easily and have lots of available high performance parts.

Thanks for all the great replies. I'm going to pass. My wife will be happy - one less "project" sitting in the garage!

A boat anchor would be a good use for it!
