I have a Buick 300 but interested in replacing with a Buick 350. Are the motor mounts, bell housing and valve covers identical or different?
I'm not sure on the motor mounts, but the bellhousing on the 300 is the same as the 350. The valve covers are different at least in appearance. The 300's are styled to look like the nailheads of the era, the 350 uses the more modern style.
