Yah! Get in line!

D1AE-A,-AC,-A2C were the early 400 blocks( I think they might have all been smallblock pattern). .060 on a 400, I don't know but it sounds like you're going to wind up with either a steam engine or 400 little pieces.

The only reason a 351W is better than a 351M/400 for buildup is due to the availabliliy of aftermarket goodies. The 351M/400 engines have better specs to start with, but they have not been fully developed. But now there are parts available which have the potential of making the 400 the best choice for building.

Actually the oiling system is what makes the Windsor a better build.

Amen

The oiling system is only a problem at high RPMs, however there are fixes available for it. I used to make my '67 stang w/the 70 351C-4V scream, and never lost oil pressure. Oil pressure isn't really important anyway as long as all the parts are getting oil. A high volume oil pump insures that.

I need more posts so I can put my truck picture in my profile.

here it is.

Oooooohh yeahhhh!!!! Nice truck.

I don't care if it's got a squirrel cage under the hood, it's BAAAD just sittin' still...

Kudos! Mover

The best thing that you can do with a Windsor is to put a 400 crank and Clevelands heads on it.

Another good forum on the 400. Read it and see how it goes to hell. Too bad some of these people just don't live right next door. The very last post by the webmaster is good though. Someone sits there foot down. I'm just glad things don't go bad on this site. http://www.ford-trucks.com/dcforum/DCForumID12/167.html

Kevin,

I don't want to start engine wars here. Actually the Windsors are very good engines. I just prefer the 335 series, and that's all.

I just have one question.

If you put a 400 crank and Cleveland heads on a Windsor block, does it become a Clevor or a Windsland?

had a 351m IN my 79 bronco, put in a 400, couldnt tell any diff. had a edel intake, holley and schneider cam, it should have been alot faster imho. i think its a pig

A stock 400 may have as low as 8:1 Compression Ratio. If that cam you used has a long duration, it will never develop much power. To wake up a 400 you need to increase the CR first, then pick a cam based on the CR and rear ratio.

What is the duration of the cam?

Eric,
I would not recommend building a 400 block that is 0.060 over and I am sure that you can't go another 0.060. Also check the casting # on those heads. The closed chamber heads are D0AE-H and D0AE-R and are 62.8cc. The Boss heads are D1ZE-B and are 66.1cc. The Boss heads are an open chamber design. The CJ heads are D1ZE-DA and D1ZE-GA and are 75.4cc. These are open chamber heads. Watch your compression, if those 10:1 pistons are for a 351C, the CR will be higher in a 400. Also you need to know which head cc to use in the calculation. There are so CR calculation web sites. Just search on Compression Ratio.

70sFORDs,

Yes, you can put 4V Cleveland heads on a 400. I have one in a '53 F100. You will need adapter plates(Weiand) to mate a 351C-4V Intake to the 4V heads, because the heads will be further apart due to the additional deck height of the 400 over the 351C. You will also need a Mallory Unilite dist, because the raised position of the intake manifold will interfere with the Ford and most other distributors.

Now, the question to ask yourself is: Do you want to do it?

The answer depends on what you want out of it. If you want a hot drag car like a mustang it's OK. If you are putting it into a heavy vehicle like a Bronco or truck and need torque don't do it. There are better ways to build a 400 than 351C-4V heads

Actually the closed chamber heads are D0AE-H and -R, there is also closed chamber D1AE as well, no D0HE's though.
