I've used a spreadbore 4160 Holley on many of my Firebirds. It is close, main problem is the center stud can't be too tall. The GP I would think has plenty of room. (Firebird hoods are really close to engine)
EDIT: I think they were 4165 models for spreadbore. Maybe look for a spreadbore Holley?

Believe 4150 refers to having a pair of metering blocks on either side of main body, with the 4160 is a vacuum secondary type, and has a plate, instead of a block.
Holley did make an aluminum bodied carb in the mid seventies to early eighties, it was the 4010/4011 series. I might have one in stock, but it would have to be gone through, and I would have to think or doubt parts and or gaskets are still available for it.
