Okay, I am new. So first hello. I have a 69 Nova. The motor was just built this month by a specialist. It's a 468bb, with 571HP and 601lbs torque. I currently have a Muncie 4 speed. I ran all the numbers, it was built in 65, or 66. At that time they did not stamp it with an A,B, or C indicating M20, 21, or 22. The top does have a stamp, looks aftermarket that says M22. Regardless I know I will need to upgrade sooner or later. I want to keep the same transmission. Is there a place to buy aftermarket 'guts' that will help it stand up to the torque.??? I am not racing it, its street driven, but I do get on it for fun now and then.

Any help locating aftermarket 'tougher' parts would be great. I really can't afford a new transmission for 2K.
