Re: 454 366 bbc

There are 3 talldeck engines-366,427 and 454.
I have a 427.
The easiest way for me to tell them from a regular big block is the distance from the top water pump mounting bolt hole to the surface of the blocks deck.
It's about 3/8" on a tall deck and even on a regular big block.
The actual difference is .4" as measured from the center of the crank to the top of the deck.
You can't over-rev a t.d.!(Well,you can one time!Then look for another one!)
Mike.
