Just getting into big blocks, don't know much about them. Need as much info as possible on tall deck 454's. My dad has a mid 80's RV with a low mileage 454 in it that I suspect is a tall deck, and I wonder if it may be a good candidate for a Camaro transplant. Would like to put aluminum heads on it with a more radical cam, too. Also would like to go with a single plane intake.

tall deck blocks are aftermarket blocks
Dart- donovan -Brodix etc.
there isnt an OEM tall deck block period.

To my knowledge there isn't a oem tall deck 454 only a 427 and a 360. My bro has a 427 tall deck in a chevy dump truck.

Pretty sure there was a 366 & 427 tall deck truck block. You'll likely need spacers to get an intake manifold to fit, you'll have to address the distributor, and you'll have to address the different exhaust location. That's what comes to mind, anyway.

Thats it 366 not 360 .

Man, I'm confused! Just got thru lookin at several websites, some say no tall deck 454, others said yes. Standard deck 454 would be cool, too. Hopefully I'll get some numbers off the block tomorrow.

There's no such thing as a tall deck 454!....Why do you think it's a tall deck?.....Anyway, this motor would be an excellent candidate for your Camaro!.....It should be a 4 bolt main block with a cast crank and cast pistons.....A nice pair of aluminum heads would be a good idea along with a nice "choppy" idle cam and headers.....Make sure you match the cams power range to the single plane aluminum intake manifold or better yet, go with a nice aluminum high rise, dual plane which will start making power off idle to around 6000 rpm!

Thought it may be a tall deck because of the chassis it's in, big azz rollin condo. My dad said he thought the tranny was a 400, too. Now, just gotta figure out where to mount that Onan generator in the Camaro.......

I agree with the above post.

I'm pretty sure if it is a mid 80's big block it is NOT a tall deck. Get that engine!

You can tell a 10.2" tall deck 366 or 427 block b/c the top water pump bolts are like 3/4" from the decks vs like a schosh over 3/8" w/ a standard 9.8" tall block.

Spot them from 6 feet away in a truck!

Huh??

Wrong, there's three!

The 366 and 427, Mark IV's and the newer Vortec 8100, morphadite 496 engine.

All the rest are GM over the counter blocks unless they are aftermarket like already mentioned.

the 572 is a tall deck.25534368 - Sportsman Tall Deck Bow Tie Gen VI, 10.200” Deck Height

Thanks for the info, guys! My dad tried to get at the casting number today with no luck, said he will try a couple tricks tomorrow. The 454 and 400 tranny have 36,000 original miles on 'em, so I don't think I'll be tearing into them any time soon. Engine fires right up, runs smooth, does'nt leak, and the tranny feels tight and shifts perfectly. After doing a ton of research on the net I don't believe there is such a thing as a tall deck 454, which is just fine with me (cheaper). After I get that casting number and figure out what kind of C/R I'm looking at, then I'll have a better idea on which cam, heads, and intake I'll need.

As you now know..there is no 10.20 tall deck oem 454.With only 36k on the engine...it is a prime candidate for a few lbs of mini roots inspired boost in stock form.
