Any Chevrolet Big Block Experts Out There?
I have a '71 Camaro with the 454 (probably not original) that I'm trying to identify. The casting # 14015445 and serial number above the timing chain cover is CG3328876. The casting number tells me that it is a 1978 -1986 (2 piece rear seal) but I can't decipher the serial number. Can anyone help or just steer me to a 454 forum/club?
Thanks guys,

The book that I have doesn't give alot of information on that one either other then the c in the serial means that it was ment for a car and that it can be either a 2or 4 bolt main

I know 1970 some camaro's had 396 factory installed rare but they made them ( sometimes called a 400 ) from the factory
454 were never put in a production camaro except for the aftermarket dealership swaps and at that time 427's were the most common . Yenko nickey and motion to name a few
I am not a expert by a long shot but have ran BB chevys in my cars for at least 40 years ( I have two 69 Camaro's both with 454's one stripped down body and engine both awaiting my attention my driver has slightly modified 454 60 over 4 bolt steel crank I built many years ago .
I have many books on the chevys , camaros and engine numbers and codes but all are stored away some where in the horde and its been 10 years since I looked any numbers up .
I would guess google would be your friend even finding a forum or pages of info .for what you seek should not be too hard
as a kid I would have loved to have had google and youtube .
sounds like a great project ? toy you have

I drove a 71 Camaro SS 396 back in the day. In that model year, I only remember seeing them with a 350 or 396. Wish I'd had a 454. Might have been able to catch those damn 440 cudas of the era. The 396 and I couldn't quite get that done. Sounds like you've got a fun project there!

You have to drop the oil pan to determine if 2 or 4 bolt. My book of numbers shows no 2 letter BB 454 engines. Most likely a counter exchange. 0 -
Here is some info I found on the block. "They were crate engines, and built with whatever 4 bolt blocks Chevy was producing at the time, and 1978 -1990 was when those crate engines were offered. And by the same token, it could have been the same block used in a light truck with a 454. Only truth is that it's a short deck block."
So it could be a 2 or a 4 bolt main according to the link below. Just according to what was available.
Here is a listing of Chevy big blocks.

Not any longer, simply remove the oil drain plug and insert the 5.5mm inspection camera. It is being done quite often now to verify rare engines.select-fire said:You have to drop the oil pan to determine if 2 or 4 bolt. My book of numbers shows no 2 letter BB 454 engines.

Thanks for the replies guys. I have a 2 bolt block w/ 2 piece rear seal. Given that, it's a '78-'86 block. My problem is that I can't find anything about what seems to be a weird s/n (above the timing chain cover). What I'm trying to do is purchase new head gaskets. I have found that are many 454 gaskets and the first pair I bought blocked some of the cooling passages. At $100.00/pr, I don't want to buy the wrong ones again. That's why I would like to nail down just what this engine is. 0
