I have an 80-85 block, I know that my block is the same as the pre 80 SBC other than having a RH side dipstick. Here's the question, how does an early SBC differ from one that was used in an IROC camaro (88)?

I'm thinking about using a centrifugal supercharger kit for an IROC camaro. Are harmonic balancers interchangeable for these years? Are the accessory bolt holes on the side of the head the same? Basically what I'm trying to figure out... would everything bolt up?

your correct dip stick is one thing. but will have no being on your project.

I am not sure when center bolt heads started? you have center bolt valve covers on that motor??

No, I have the 80-85 block. Side bolt valve covers. I was wondering if the crank/ pulley/ harmonic balancer are different on an 88 SBC. And if the 88 SBC has the same accessory bolt holes in the side of the head.

Basically, if there is a centrifugal supercharger bracket/ pulley setup made for an 88 Camaro, would it fit on my early SBC block? Would the pulleys line up?

I think the front of the engine you are OK. If it has a 1 piece rear main seal you will need a different flywheel. Also it should have the provision for a roller cam.
