    I have a complete 3 speed manual trans setup, for a Buick 350 from 69 skylark, trans , bell housing, flywheel, clutch fork,Z bar,ball, brackets, pedals etc.. I know flywheel is different , but can the other parts be used for a manual trans conversion for a BBB.

    tubecatgs Finally a 4 speed......

    I have a 72 Skylark custom convertible 350 that had a 3 speed manual on the column. I was able to use the pedals, fmywheel, z bar and most all the linkage for a 4 speed on the floor swap. There are specific parts for a 3/4 speed BBB vs SBB like bigger clutch, Z bar etc.

    I have a 455 i was thinking of swapping for the 350 and started a thread on it if this helps at all...

    Good luck!

    The whole setup might switch over but the individual linkage pieces from the z-bar including the z-bar to the fork including the fork are different.

    Thanks Dave, I assumed the differences due to the block,you helped a lot. I'm going to list it for sale as a complete 4 speed setup for a 350.
