Replacing the tired Buick 231 in the Commando with a V8 Buick 350 Dauntless. Found a complete running 350-2V block from a '72 Skylark for $90, and then just scored a completely rebuilt 350-4V engine for a '73 GS for $150, and it has HEI. Both the new 350s have flexplates... I have a spare 225 at home, with a spare flywheel and a BOP bellhousing. Will the 225 flywheel fit on the Buick 350? Going to an SM 465 and Dana 20 combo. Thanks, and any advice or knowledge would be greatly appreciated!
