BOP Saginaw G Body Bell Housing?

[joesregalproject]

Is there such a thing as a BOP Saginaw bell housing for a g body? I'm looking at the 4 speed route with my Regal and I can't seem to find a ton of info on manual trans g bodies without Chevy engines. Any insight?

You'll need GM p/n 563441 for BOP engines with 10.4" clutches, p/n 1378868 for the lower cover. The fork, dust boot, & ball stud should be the same. From my research. There is no 11" for the BOP's. It will be the same for 3 & 4 speeds, should be the same on the T50 5 speeds. They are harder to find it seems, but there gotta be something hidden out there. Any model could have one to including Chevys with 231's.

I have a 441 bellhousing, plus another BOP bellhousing from the 1970s. Side-by-side they look the same, and the 70's cars often had 11" clutches, so I suggest that if you can find the bigger 168-tooth flywheel, you could make it work. I don't have an extra curved G-body fork, but they can be had on http://www.4speedconversions.com. I had a brief moment when I thought I'd put a Buick 455 in a G-body, and then I got an estimate of the rebuild cost and decided to go with a 350 Chevy.

Oddly enough, I used a BOP bell housing I bought at a swap meet years ago. It turned out to be from a 60's Pontiac OHC-6 engine. It fit my Pontiac 301 perfectly and I used the regular straight Firebird clutch fork. It cleared the Bonneville floor pan easily. When I had a Pontiac 400 in my Chevy Malibu wagon I needed to pound the floor pan in for clearance with a straight fork. But the Bonneville floor pan seemed like it was made for the fork to fit. So I guess all G-bodies are not the same. The OHC-6 used a flat finger 10.4" diaphragm pressure plate. But I managed to get a stronger bent finger 10.4" diaphragm plate to fit by using the old Chevy straight 6 fork ball stud and a short throw-out bearing. The stud is shorter than the standard V-8 size. GM used to offer 3 sizes, short, medium, and long, and Lakewood made an adjustable ball stud.

I have a g body BOP bellhousing. I'd sell it shipped for $140 if you want it...

Sucks that you didn't go with the 455. Just a stock rebuild of one to 1970 stage 1 specs gets like 400hp and over 500ftlbs, plus it weighs as much as a SBC. But BOP stuff sure is expensive.
