Manual trans Options for LA 360

Last choice but easiest to do is the A833 OD. The overdrive will handle the power. Even more so because the car is light. If it were a heavy B body, I'd think twice about slamming years without mercy.

The second choice is a catch 22 because there both good ideas and transmissions.
The Supra 154 can handle good power but does require the quick time bell and mods to make everything work. Just like the Tremac.
