Lightweight Turbo-Hydramatic 350 Transmission - This transmission will never run, but it sure makes a great display and works well for anyone setting up a street rod or race car chassis for motor and transmission mounts, steering and header clearances, and more. This authentic plastic reproduction weighs less than 10 lbs. Think of the time you'll save using this lightweight compared to a cast original! This transmission incorporates metal threaded inserts to bolt on mounts and oil pan. Removable 6in. extension makes it easy to bolt on alternate extensions. Bolts directly on to 350 Chevy Block.
