454
Not sure what part of the country you are in, but if near New Orleans, Louisiana, I have a 454 with rectangular heads, complete from carb to starter that I am not going to use. Was going to place it in my vette but modifications to do so became cost prohibitive, so I went with a SB 383. It is a car BB, not a truck BB, cast intake, bone stock.

What year is the 454? Is it a 2 Bolt or 4? Any idea what type of vehicle it came out of?
Do you have the casting #?
Thanks for your time,

Morning:
I pulled it from a '87 GMC p/u; was attached to a Turbo 400 tranny - definitely a short deck - can get the casting numbers later tonight (it had gone down to 25 here last night so not planning to go out to my shop until it warms back up to at least the 50's).
I pulled carb, intake, heads, and oil pan off to verify condition and check rotating assembly; other than carbon build-up on flat-tops and heads, its fine.
It might work for your purposes and it certainly looks impressive, but for me it was more cost effective to build a 383 SB (considering horsepower and weight differentials)...
Note: The cast iron intake is a heavy beast - definitely needs to go to aluminum - Since it is already partially down, a good hone, rings, bearings, and new oil pump would be in order; rectangular heads not as good as ovals but a little porting could solve that...

Some added info
Added info:
The block is classified as a LS-7; produced from 1975 to 1987; Application: either passenger and/or light truck depending on bore from 396ci on up and what was originally ordered... (Mine does not have the XCH stamp above the timing chain cover)...
As far as rebuilds are concerned the cylinder walls of these engines are the more preferred model if increasing bore size because of the added thickness that easily handles up to a .060 re-bore without over-heating issues...
Just curious about why the need for a four (4) main versus a two (2) bolt version??? A standard two (2) bolt main with modified new main studs should easily handle upwards of 650 hp with no significant problems...
Regardless whether or not you could use my engine, good luck in your search for the 454 BB, because they are getting relatively harder to locate in (un)re-bored original condition...
Respectfully,
