I know, horrible picture. I'm at work and am blocked to most imaging sites. Checking out a 454 and want to make sure it's a 454 standard height. I am awaiting casting numbers. A bit greasy for the owner....can't see them too well:)

Unless it's been rebuilt that way, only 427's were tall deck and these were in trucks. There should be about 1/2" between the top of the water pump to the deck of the block to be a tall deck.

Thanks for the reply. The truck is a 73' with a 454. Just want to make sure that I don't waste 400mi and a day to find out the block is something else.

There were 454 talldeck block's produced(Bowtie) but no 454 tall deck engines.
Still get the casting number.

You could get the 366 and 427 in tall deck production engines in heavy duty trucks only I think. ( Grain trucks and such ) 454 came tall deck in a few marine applications I think and of course bowtie blocks. I think I remember reading Mercruiser using some 454 tall decks in marine applications only. I could be wrong. Not positive.

Casting # is 39999289. Std. height 454.

I'm torn...this is a 73' 3/4 ton truck w/454 & 400 trans. Rough, but I want a truck and a BB, what's a guy to do?
