The trans came with the 455 I bought that had a rod knock. I am guessing its good, but sold as a core. It came behind a 1975 455 that was installed in a 1951 Buick (!). Its a long tail shaft unit, complete with torque converter, dipstick, and flexplate (after I finish the balancing act on the 455 with a manual flywheel!). $75.00 with pick up here. I really dont want to ship, but can help with delivery within 50 miles or so... ws
