Will it fit? Read the BBC swap sticky in the top section of this forum.

Re: 454
The last "car" that came with a 454 was in 1974. Trucks still had a 454 option up to when GM started switching over to the LS engines. In 1991, the Mark IV engine was phased out and the Gen V was introduced. Luckily, that engine only lasted a few years before the better Gen IV was introduced. This was the beginning of the Vortec engines.
The gazillion aftermarket parts available for a BBC are normally designed for the pre 91, Mark IV engine so you're looking for a 454 from the 70's or 80's.
Externally, the short deck BBC is the same dimensions from the smallest 396 up to a 540 (which can be punched out a little more). The tall deck blocks are designed for 5 ton trucks, school buses etc. The deck surface is .400" taller to allow for a bigger piston with an extra compression ring. These were available in 366 (6L) and 427 (7L) displacements. Although the 427T has performance potential, a tall deck block makes an engine swap a lot more difficult. There are no OEM tall deck 454 engines.
Good luck finding a good 454 for an inexpensive price. If it's being sold cheap, there's usually something bad about it. It can be a lot cheaper to just buy a stock replacement engine or even just a short block and start from there.
The only factory component in or on my engine is an alternator. Everything else is aftermarket. I gave up on factory parts many years ago.

Re: 454
'70-90 3/4 or 1-ton trucks are the most common sources... 1990 and earlier are 'Mk IV' engines, which have the strongest aftermarket, so its probably the best choice.

Re: 454
After 1974 BBC's were used in almost anything and everything considered heavy-duty, or industrial like; tow-trucks, dumptrucks, delivery trucks( Ryder and U-haul etc.), R/V's, some combines, and other farm equipment like irrigation pumps and other stuff you might not think about. If you find it difficult then your not looking hard enough.

Re: 454
If you want to ever want stroke your bbc more than 4.25'' you NEED a tall deck, unless you get a aftermarket block and they start at 2500. bare iron. I got 525ci. out of a factory 4 bolt tall deck 427 that only cost 300 bucks. Dont let .400 taller scare you, the biggest difference on the outside is only the intake.

Just look for a short deck 454 if you just want the easiest and cheapest way to put a BBC into a 3rdgen. I'm not saying it will be cheap, but a std deck BBC like a 396 or 454 is cheaper to install than a tall deck block, and easier to get parts for too.

Re: 454
The biggest problem with a talldeck in a third gen is exhaust. There will be heater or brake booster clearance issues but headers will need to be custom made. Even the cheapest headers available are the Hooker swap headers and they're not cheap. They're also designed as a street header. They're made for a short deck block and factory heads as a basic engine swap. Install aftermarket heads with raised exhaust ports and fitment becomes difficult. Stick those heads on a tall deck block and the swap headers become useless.
