If it IS a C, and you want EFI, this can be FUN!
You'll want a single plane intake for it, get injector bungs welded in the runners so you can run EFI rails on it, then pick up an elbow from CHP to mount where the carb would go. From there, you run a standard Mustang-style throttle body.
You might have to do something funky with the distributor.........
Convert the bad boy to roller with crane link-bar lifters, and run a custom cam
Yowzah! It'd be quite the weapon!

It can be confusing enough for a Cleveland newbie..... suffice to say '70 model year through 74 model year. Late 69 was the casting date, not the model year of usage.Originally posted by lincolnmania

Personally, I think a carbed 400M swap would be a better idea than a 351C. With head work and a cam, a 400 can be a real screamer, and have stump-pulling low end torque. Just ask MRLTD about the 400 in his Bronco.Originally posted by Roach IIINick

My worst enemies are those who presume me to be harmless. They cannot imagine how much I resent and disdain them, or just how great a threat they would face if I could get at them. Everything in their behavior speaks of insult and presumptuousness, and for now it is all I can do to make constructive use of my anger toward them. At this time, I just make a list of them and keep a watch on. Some day, with the help of time, space, and circumstance, I will be able to humiliate them properly - not in a manner they would enjoy, but in a style calculated to make them wish that they had never been born.

Are the deck heights actually different between a 351M and a 351C ? I know the heads and cam interchange, but I know little about these motors. I seem to recall reading that the intakes interchange too, which would (at least to me) mean that the deck height is not different.86 Lincoln Town Car (Galactica).

There is no M in a Ford 400....Originally posted by 88MercWagon
It is kind of like guys that say nos as a word when talking about a nitrous system. Yes, it is common slang in some circles, but it just isn't right... A 400 is definitely a potent moter when built right. 400+ cubes and Cleveland heads is a great combination. There wouldn't be 400+ cube Clevors if it wasn't. You just need to sonic check your block as all 335 series blocks (351C/351M/400) are subject to very thin walls. It doesn't take much of a cam to make over 400HP at low rpms. If you are going to do it, you might as well bolt on 351C 4V heads and use a 351C 4V intake with the adapter. You will need custom headers either way and a double hump oil pan.

The intakes do NOT interchange without an adapter. The deck is higher as I described in my previous post. The 351M/400 intake is noticably wider.Originally posted by gadget73Comment

Deck heights according to wikipedia:
http://en.wikipedia.org/wiki/Ford_335_engine
351C is 9.206 in.
351M/400 is 10.297 in.
the 351M was a destroked 400 with a 351W crankshaft.Last edited by Roach III; 12-24-2006, 10:03 PM.Project \"Fire and Ice\":

I was under the impression that a 351w was smaller than a 351c deck height wise... 9.503" or 9.480" (69/70' blocks) is bigger than 9.206"... is wiki is wrong?Originally posted by Roach IIILast edited by JeffBoudah; 12-24-2006, 10:33 PM.Comment

It isn't actually a 351W crankshaft. The main bearing journal size is the same but there are several differences which prevent a direct bolt-in. It does share the 3.5" stroke of the 351W. The flywheels are interchangable as they both share the early small block imbalance of 28 oz. .Originally posted by Roach IIIComment
