Good observation. Is it safe to assume the A body specific bellhousing isn't necessary with a hydraulic release/throwout bearing?

It doesn't matter then if you are activating the clutch hydraulically. But it is critical with stock linkage as the typical bellhousing puts the clutch fork into the floor where the gas pedal is located.

My original '81 Malibu used the Chevy V-6 and Saginaw 3 speed trans. The stock clutch fork was bent to clear the floor. When I put a Pontiac 350 in I used a standard BOP bell housing. I had to massage the floor with a sledge to get the fork to clear. That I understood. But right now in my '83 Bonnewagon I have a Pontiac 301, a 1960's Pontiac OHC-6 bell housing, and the standard Pontiac fork cleared the floor with plenty of room. I just figured the Pontiac floor was different from the Chevy. I used the stock Malibu linkage with all of this.

I’ve been lucky a was able to get both the flywheel and bellhouseing from my brother. Hold on to it in hopes to put it behind a 68’ Olds 350 I’m wanting to get rebuilt.

I used a regular 621 bell housing on my first Malibu 30+ years ago. The floor had to be bashed in right where your foot rests for the gas pedal. I personally would never do that again. But I guess it's acceptable to some people. There is a reason GM tooled up BOP bell housings with the lowered pivot ball position.

Well...can I say before we knew any better...I had a Lakewood scattershield in the SS with a purdy straight clutch fork and the same battle damage to the trans tunnel. I kinda wonder what it would take to run the appropriate Gbody clutch fork. I'm sure the pivot ball would need to be relocated and clutch fork window would need to be relieved to accommodate. Which raises another question, would my z-bar and linkages work with the gbody fork.

At some point in the venture, I did buy another Lakewood scattershield but with the BOP pattern for my Buick. I should drop the P as recently I learned it doesn't have the starter pocket for a Poncho engine. Same deal here with the Gbody clutch fork but it brings up another question regarding SFI ratings from the butchery of the BH.

I just did a quick search. I don't see the Chevy bent-down clutch fork at all. It exits the bell housing window and drops down sharply to clear the floor pan. I always wondered if you could use it with a BOP bell housing for more clearance.
