For the correct answer it depends on which engines you are call a small and a big block. So if you are comparing say a Buick 300 to say a 455 buick the answer is no.
Pretty sure they are different part numbers. The parts group number is 0.683. At least this is what I recall. Maybe someone can check this out.
I just installed a 455 in my original GS 350 with 4 speed. I also used the original 350 bellhousing and clutch linkage.
Thanks for the info guys. I just picked up a used buick bell and wanted to make sure it was going to work before I puchased it.
350,400, 430, 455 engines all use the same bell housing 1967-1975. It is part number 9785581. I recall the 300-340 and 215 engines used a different part number. It would be easy to verify one way or the other since the number is usually stamped on the inside of the bell housing.
I understand that, but does a 300 -340 housing carry the same part number? For example, there could be a difference in the clutch fork area and not the ears.
They wouldn't be interchangable so wouldn't think part numbers would be the same... Stranger things have happened. Here's a 215 bell part # 1355746 Here's a 64 300 part # 9774035
Part number 9774035 is what my research also shows for 300/340s. Apparently there is a diference in the starter housing configuration. This may be the one starter hump versus dual hump difference.
Iam not sure If all had the dual trans bolt pattern the gs ones had bolt holes drilled for the ford built three speed. I have seen some that had bosses cast in but not drilled for the three speed.Glenn
Hi, The 300 is a fully enclosed Bell with a small inspection cover (if you could call it that) vs. the newer 350/455 that has a large removable inspection cover and large opening on the bottom any BOP (Buick, Olds, Pontiac)will bolt to any 300, 340, 350 400, 430 or 455 just have to make sure they are either Dual starter or have the correct starter side as they did come RH or LH depending on orginal application The 215 is totally different as is a Nailhead Bell Housing as someone stated Regards,
11" clutch may not fit inside the 300 bellhousing behind a 455 - bolt patterns and length are the same
