Ford 400ci 6.6L

[treegump]

Anyone know anything about the 400ci motor?

I plan on looking at a 79 F250 with a 400ci, 4spd, 4wd this afternoon. I was led to believe that the 400 is bastard motor (from a ford fan) - didn't know if you guys had an opinion...

Oh, and supposedly has an RV cam in it to help with pulling (per the seller)

I once owned a ford F250 with a 400 engine. It run good and pulled a horse trailer good too.
An old timer ford mechanic said the 400 was a modified 351, I think He said they were bored to make the 400. IIRC

Pretty sure they like that motor in the hot rod world

Afaik, every 400 cid gas engine ever made has been good.

The 400 is a good engine for towing.

What was not to like about a 400 CI gas motor or a Diesel. Never had any experience with the Ford 400, can't help you there. Other than loving gas I would say it would be a good pulling engine unless it is wore out or has issues.

Got the 79 F250 with the 400 in it.

Need to update my profile pic and signature.

So far how is it doing for you. Great to hear from you again.

Pretty sure my f600 wheat truck has a 390 or 400 in it. It's really not terrible just sucks the truck is only a 4 speed with a 2 speed rear.

Someday I'm thinking a 5.9 and a 6 speed MD trans would be nice and keep the 2 speed rear.

It's running rough but it's not the motor's fault. Someone decided it was a good idea to put an edelbrock carb on it before changing out the plugs.

The seller gave me an HEI with new plug wires, as well as a block fuel pump and regulator - and body mounts. If I come across a stock or holly - i might switch to that, but we'll see.

And I know this is a chevy page - but I've always valued your opinions/experiences. It's always great to visit.

You guys know of any forums good for these old ford trucks? Maybe or maybe not for specifically 70's models since I do have an 88 bronco that I plan on keeping for a while..

You might try powerstrokenation. com, I think they have a discussion area about gas engine Ford trucks.

I am not a member of that forum of course, I just stumbled across it one day. No I am not about ready to jump ship to a power stroke guys....
