Some early 2004Rs have only BOP mount pattern.
The CQ,CZ,OZ or KZ coded Trans would be better for a V8, they'll have the highest rpm Auto shifts. BQ/BR code would work well with 3.42 gear, it'll shift around 4700-5000rpm.

BOP Only:

That is the first BOP-only TH200-4R I have seen. I have only ever seen CBOP patterns on a TH200-4R.

They're not very common.
All Chevy cars came with BOPC+Chevy UniBell pattern.
There are no Chevy only Bell patterns, as far as I know.
BOPC = BuickOldsPontiacCaddy

Yeah, the BQ/BR codes are for Buick Turbo-V6 w/3.42 gear which don't Rev like a SBC.
The CQ/CZ = SBC/305, OZ/KZ = BOP/307 codes Auto shift around 5500rpm and are tuned for 3.73 rear gear.

Lonnie @EA/ExtremeAutomatics has a Valvebody calibration machine & can setup what's needed. I think Chris @CKPerformance also has one.
