I voted 390. Strong rods, quench heads that flow good stock and unbelieveable ported, deep skirt high strength block, bulletproof cranks, all for about 625lbs, much less with aluminum parts.
There's just something about open chamber heads that I dont like. Oh wait, it's the pinging!

Yea,I guess so,I just know of several 351m/400's that had the bottom end fall apart due to relatively weak cranks.That and like I said,the FE has more potential IMO because hardly any serious parts are made for the 400,in the case of the FE,how much hp do you want?Not on the ballot,but I'd take a 460 over either one in a truck.

Since everyone says 390, I'll start out saying I'd take a 400. IF I had a choice(and the money)to rebuild either one of them.
Stock, I wouldn't want either one of them, but If I had to say one stock it would be a toss up.
10MPG, I don't know where you come up with saying hardly any serious parts are made for the 400, b/c I can assure you if you say that statement in the 351MC400 forum, you would have everyone disagree with you and show and tell you what abuse they put theirs through.
Like said above if you have the money to rebuild either one I'd go for the 400.

I voted 390. I bought a brand new 77 F250 400 auto. It was ok and never gave me any problems but I like the 390 better.

10MPG,
Those links that I posted in Post #18?
...you were supposed to click on them to see these awesome parts that you say aren't available.
There is a user on here that has a 400 that puts out over 700 HP with these so called unavailable parts.
My 400 went 319,000 Km before the timing gears & chain were stripped so bad it would run.
The 351M/400 had oiling issues but that can be rectified.
Research !
Me, I'll stay with my 429

to build one fresh is a toss up but for a used truck with a stock motor i'd go 390 mainly because i've aleady blown up a 400 (darned oil pump) the one thing the 400 has though, is that a 400 truck is easier to put a 429/460 into.

I am biased, I own an FE. From an engineering standpoint, the FE is the better of the two motors. Y-block design is very important, just ask the LS6 chevy guys. However, any motor, be it a volkswagon, or Volvo can make horsepower. Generally speaking most popular motors will last a long time when well cared for. All that leaves us is bias and softspots. I have a softspot for the Y-design, shaft mounted rockers and f#@ked up manifold design, e.g. taking the pushrods out to get the manifold off. That is why I own a 292 (easier manifold) and a 360. Funny, I also own a pontiac with a 3100, same crap with that manifold.

I think both have potential, but I think the 390 has more. The Fe's are desinged to hold up to higher HP and Torque numbers. It's a big block, and is a more nervous engine stock. And before I get grilled I'm comparing his 72 390 to the 78 400.
