I had an 81ish F-250 company truck wth a 400 and it was the biggest POS I ever had to drive, although the 79 with a 302 that preceded it was pretty bad. The 79 was ordered as salesman's truck and not expected to do any heavy work. Then I got it. The only gas it would burn without pinging was Amoco "white gas" at the time.
The truck that followed it was an 85 F-250 with a 460. That one was a brute, but I'm glad I didn't have to feed it.

The 427 had the larger cylinder bore and the 428 the longer stroke. The 427 had the low riser heads, similar to the 390/406 heads, then the "high riser" for racing only (Mostly drag racing) and then the mid riser heads that were the most common and what most of the line production 427 equiped cars got.
There were also the tunnel port heads and as mentioned the SOHC heads.
The 427 was, if I remember right, much more of an expensive, race-oriented engine, with the single quad rated at 410 hp and the dual quad at 425. The 428 was cheaper to produce and wasn't tuned all that hot--345 hp was a common factory rating.
I know this is an old thread and somewhere in the middle after debating the 4 27 4 28 and 429 some somebody suggested how about the 351C the 351M and the 351W well Howell how about my favorite engine the 351 cobra jet
In reply to Shohohn :
That was a 351C.
The 400 was not a 400M, it was just a 400. Ford called it a Cleveland. They made the 351M after they stopped making the 351C and realized that they couldn't make enough 351Ws to meet demand, so they stuck 351W cranks in 400 blocks and called it the 351M... for when you absolutely must have an engine that makes power like a small block but weighs as much as a big block. Supposedly the intake manifold had a casting that would accomodate a 4bbl carb, but they only ever made 2bbls, so the casting thickness was a couple inches deep in spots. And in those days, intake manifolds were iron.
How about a 462" MEL to add to the confusion?
I'll crawl back into my hole now.
In reply to Pete. (l33t FS) :
We had 3 Fords when I started driving: a 1970 XL convertible(LTD) with a 390, 1977 Country Squire wagon with a 351M(and fake wood!), and a 1978 Lincoln Continental Towne Car with a 460.
I'm pretty sure all-3 were completely stock, and the wagon with the 351M was noticeably quicker off the line than the other 2. Of course there could have been a variety of reasons for this that were beyond my comprehension at the time, but all-3 cars were similarly well-cared for with under 100k on them.
My dad always had 70s Ford trucks when I was growing up so I have a soft spot for the FE engines
