AC means it's definitely not a COPO 427.

Inner half AC box for BB is different than SB. I can get a photos if needed.

Not needed. It has to be a small block with X44 and AC. And the tag data says it isn't COPO.

Yes pics would help greatly!!

[Cableguy1979]

I've read they made big block cars with ac. I would probably agree it's not a copo but are you saying GM didn't make a x44 with a big block and AC? Kinda hard to belive since you could get any of these options added. How can I identify small block Ac firewall versus the big block AC firewall?

Pictures are alway beneficial.

Yes, they made big block cars with A/C, but ALL of them would have been X66 or X22 cars. The ONLY big block car with and X44 tag would be a COPO. No COPO had A/C.

It is 100% certain that your car came with a small block. Period.

I only post this because guys are posting things about big blocks with AC, and i don't want you to get your hopes up thinking this car may have come with a big block. It didn't.

[Cableguy1979]

That's fair. If anyone can post a picture of a big block firewall with AC that would be much appreciated.

BB Camaro AC box inner half.
I'm told same as V8 Firebird.
Very pronounced dimple vs small block.
