This is a question for the mythical Jim Forbes.
Even though I've heard it called a truck block, probably from the earlier
348/409 engines which did start out in trucks and then ended up in cars, the
427 started out as a 396. The 427 was used mostly in 67-69? (then 454)
Corvettes and a very few Chevelles, Camaros, Novas, etc. A very few of these
were aluminum (ZL1). The 427 usually was not put in trucks until it became
the 454. The typical truck big block was the 396/400/402 on the 67-72 1/2
tons, but some 427's could've gotten in there somewhere. GM now has a bored
out version to 502.
Most of the 427's had more than 390hp and the L88 Corvette, which was
advertised at 425hp, actually put out closer to 550hp. It could be bought for
the street if you were crazy enough, but was meant for the racetrack.

The 366 is a Big Block, but of a different breed. It has a taller deck
height tha n the standar family, something in the area of .6 inches or so, to
accomadate a 4th ring and taller piston. There was also a 427 "truck" block.
It really has no advantages to any other street motor, but is sought after
block for the serious racer whos limited in cu.in class. The 427 truck block
is now a hot item too.
I've heard that GM is making the same type blocks in larger cubes now, also.
