what big block is it?

[Grumpy]

Hi guys,
Just bought my dream car..... A 1968 Camaro with a big block.
I am trying to identify the engine in it.
Bought it as a 454 big block.
It has the following on it and hoping some of you guys might shed some light on it for me.
I have a aluminium manifold 3963569.
The engine is stamped behind the alternator CE360219.
I have done some search and have not been able to come up with the engine type.
I can't get behind the motor for the other numbers as its in the car.
Any info will be greatly appreciated.
Cheers Dale

MARK VI BLOCK OIL CONNECTIONS
When the Mark IV was installed in production vehicles for the first time in 1965, it carried the Turbo-Jet name on the air cleaner, displaced 396 cubic inches, and was rated at a maximum of 425 horsepower in the Corvettes.

Here’s a quick look at milestones in the big-block’s expanding and contracting history of displacement:

396 cid – introduced in 1965, with 4.094-in. x 3.760-in. bore and stroke (first production Mark IV engine).

427 cid – introduced in 1966, with 4.250-in. x 3.760-in. bore and stroke (aluminum versions used in COPO supercars).

366 cid – introduced in 1968, with 3.935-in. x 3.760-in. bore and stroke (tall-deck; used in truck applications).

402 cid – introduced in 1970, with 4.125-in. x 3.760-in. bore and stroke (advertised as 396 cid).

454 cid – introduced in 1970, with 4.250-in. x 4.000-in. bore and stroke.

502 cid – introduced in 1988, with 4.466-in. x 4.000-in. bore and stroke (Gen V block, originally developed for non-automotive applications; adapted later by Chevrolet Performance).

572 cid – introduced in 2003, with 4.560-in. x 4.375-in. bore and stroke (developed by Chevrolet Performance; no production vehicle applications).


that looks like its a 454 bbc replacement crate engine,
hundreds of thousands were used under warranty, at dealerships
or sold over chevy parts counters

whats the block casting numbers and head casting numbers?

from the info provided it looks like you may have a really nice basic performance engine, those closed chamber heads make decent power and run well on high test gas, they are designed with a good quench surface and can easily support over 500 plus hp if matched to the correct parts. Id suggest taking a compression test, and posting clear detailed pictures of the spark plugs and maybe using a dial indicator to verify cam lobe lift, to further determine its current operational condition,
Id also suggest you place a lump of modeling clay on the air cleaner and shut the hood then measure the hood to air cleaner clearance,if you have enough clearance there are more effective intake manifolds that could rather easily boost power, that intake was designed for max hood clearance, swapping to an edelbrock air gap intakes an easy 15 plus hp if you have the hood clearance required

youll need about 2.75- 3" more hood clearance for the more efficient edelbrock intake manifolds taller height
