351m/400 rebuild or replace options
I spend most of my time over on the 73-79 forum, but have been looking over here more and hoping you all have some advice. Currently I have a 351m with 72k miles that has a few issues driving me to rebuilding or replacing it (piston slap, a burnt valve or two, and maybe rod bearings). I the end I'd like to have a better than stock 400 (e.g. cam and manifold). I've rebuilt an engine before, but don't have the time or tools any more so I'm looking at three options:
1. have a local shop rebuild the engine including a 400 crank - ~$1500
2. buy a short block and have my heads reconditioned locally - I've found a few vendors on the 'net - any recommendations here?
3. buy a long block - again I've found a few vendors on the 'net with various prices
Thanks!!

I agree that Tim is the way to go. And, if you want a decent compression ratio you will need to get the pistons from him anyway as he has essentially the only pistons for a 400 that give other than the stock 8:1 compression. (And, there aren't similar ones for a 351M, so you do need to make it a 400.)
But, as Bud suggested, Tim can supply all of the parts you want, whether basic engine parts or fancy dress parts. That includes recommending a cam - probably a custom one that he's tested but made by Comp Cams. Further, he can build and dyno an engine and then ship it to you. And, if he does the build he will put his oiling system mod's in it so you will have reasonable pressure instead of the 15 psi at idle many stockers have. Or, you can have a machine shop put the mod's in - if they will, although mine wouldn't do it so I did.
Give Tim a call, but make sure you have time to talk as he will give you time.

The only reason there's a 351M is that there was already a 351C so Ford needed to differentiate that one from the other. But, there was never any other 400 so Ford didn't call it a 400M. Just a 400.

Why not have the pro do it? Tim Meyer is the guy. Ship your stuff to him, inc the heads, and he'll build it however you want it. He can even dyno it if you want.

. First of all, forget buying an engine or shortblock, unless they'll do it using TMI pistons or modified rods for 351C pistons... (or custom pistons, but that gets real pricey) ... anything else gets you a wimpy engine with bad MPG... like you already have...
. Your engine was rated like 159 netHP... TMI pistons, RV cam, new timing set, 4 bbl. & intake, and headers gets you to about 375 grossHP easily (all stock parts in good condition)...
. Check with local truck and car enthusiast shops, engine rebuilders, car shows, swap meets, and you may be able to find someone to help you at a reasonable price... $2,000 should easily do what we suggest...

I began my build with Pistons from TMeyer! And have ordered various smaller parts from him since....
I would suggest you do the same - order pistons now, then when you've saved up enough take them to an engine machine shop and tell then what you want. You want to start your build off right, and that means the right pistons and crank. For what it's worth, I picked up a used 400 - complete, for $60. The only trouble I had was getting the distributor out!

Hey Gary, as long as he already has the engine anybody should be able to rebuild a 400 for under $2000. May need to call around to find the lowest price for a machine shop, intake carb that stuff can be found used plus if a person has ant type of wrenching skills there NO REASON to not assemble there own engine. Everybody has a friend that wrenches, so ask him to help to keep cost down, i wont spend over $1500 on mine, but im not looking for big HP or anything special,if my block hadnt needed boring out id had used the stock pistons. GOOD LUCK on the build OP.
