Harmonic Balancer ID

[Carbo]

Hey guys, need help in identifying the HB on an LSX 454. Right now the engine is on my stand with no accessories and I'm trying to determine which balancer is on there. I know it's not a truck one. It's either an F-body or a corvette one. Is there a way to measure or look for markings? I've tried searching the last two days and haven't found anything. This will be going into a 69 camaro. Thanks in advance.

I have my notes at the shop but I believe the Corvette balancer face is 2.250 from the flat of the timing cover. The Camaro balancer is a bit more.

I got my answer on another board via Holley Instructions for accessory drives. A corvette balancer is 1.5" and the F-body is 2.25." That's what mine measured was 2.25 so I have the F-body style.

Thanks for the reply.
