Do you have a link so people can purchase the brackets?

I normally sell these on Facebook in the Oldsmobile groups, and on a couple of the Olds forums.
For those interested in purchasing can message me their address for a shipping quote.

Awesome engineering on those adapter plates. Truly impressed.

Someone else figured this out years ago. Then FE3X Andrew contacted me and sent some geometry to start with. I made some prototypes and modifications and added the stainless steel keyed inserts.

I’d love to see those roller cam specs

BTR asked me if I wanted to change the vavle springs every year. I said no. It's not really that big of a roller cam.

Does your kit allow the AC pump to still be installed? I assume the AC bracket sits on the passenger side head bracket.

Nice setup!

Thanks!
Yes. There will be more clearance on a SBO because the deck height is shorter. IIRC the only issues I've heard of is BBO with the TALL Mondello script vavle covers needed a different AC connection to the back of the AC compressor and custom AC lines.

If you find them I’d like to see them

Great numbers! Your serpentine brackets work great, I have them on my 88 Cutlass, like them a lot.

So what water pump and crank pulley are you running
And stock water pump is ok to run I know some serpentine belt setups you have to run a different pump that spins in the correct direction

I wonder if you have the same cam I do- BTR on a Comp core

So what water pump and crank pulley are you running

Water pump application is 1982 Cutlass w/ 5.7 diesel. GMB makes this pump, but have the rotation labeled wrong.
The reverse rotation water pump has metric threads and matches the bolt pattern of the Chevy serpentine system's water pump.
Crank pulley is a Ford 1984-1993 Mustang Gt 6 rib
Part # E4ZE-6312-AA
Pulley Dia. 6.187 X 2.625 height
This pulley can be hard to find. March makes an Aluminum replacement MCH-2008. The bolt pattern will need to be machined to match the Olds pattern. The pilot hole is bigger in the Ford unit and will not center itself on the pilot of the Olds balancer.
