What is the scoop on tall deck 454s
casting number 10114182 seller says one piece rear main seal

I was told there are no gm 454 tall decks

. what would be that max potential of this block from the intake down? Not taking into account what fuel delivery system used. I

am aware that the intake needs to be for the spread and or spacers used

If gm didnt make this then who did? Any and all info on this is greatly appreciated. I have a shot at this one in my home town. It's .20 over with all the parts. cheap cheap. like 400 bucks.

Its a GM 454 block, Gen V I believe.

Or even this....Looks like a short deck in the pics.

The different sites I found with this casting number some list it as a Tall deck and some dont. Weird

owner says its from a 90s truck and was told it could be a tall deck.


I found the only way to get a bare 502 around where I live is to order one new. I thought this may be the next best thing as I can bore it and stroke it to hop up the displacement. Only thing is the generation V thing.

What is your take?

it is a gen 5 block,standard deck,9.8.it is not a tall deck

here is a pic of the front of the block.

Tall deck or not ?

NO, short deck in the pictures !!!!

A tall deck 454 ( truck block ) has an oiling screw in the front above the timing cut out !

And 454 talldecks where all GEN IV !!!!

not a tall deck
