This is a rebuilt and modified BOP pattern TH350 I purchased Years ago for a project that never ended up getting used. Stored in heated garage. Was built for a Buick 455 drag car in the states, I believe it has high performance clutches and probably a shift kit but never ended up testing it. The owner put a couple passes on it and decided to go with a Lenko instead. Need it gone. Could be a good trans for your street strip Pontiac, Buick, or olds. Need it gone 450 OBO Purchased originally for 600 USD
