If it came with a 3 speed you are allowed to run a 4 speed.

I guess I should have clarified that, but no 5 speed in an original 4 speed combo. Also, you can run a 4 speed in an orig 5 speed combo if you wish.

The way I read the rule book it says, " any model transmission, same make as car, with a maximum of three forward speeds". To me this means you could have or a 283" Chevy in a 98 Camaro SS /GT with a 200 metric or turbo or .....

I'm not sure about this. In GT weight is linked to the transmission you want to run but I'm not sure a factory match is required in the finished car.



The rules state weight is determined using the heaviest weight gas engine with appropriate transmission available. So to find the shipping weight of a car for stick or auto application, find that car's heaviest weight in either stick or auto for the weight factor.
There is no transmission section in the GT section, just shield requirements. That means you look back to SS which reads any model trans same make as body with forward gear limits. Nowhere does it state stick must be stick or auto must be auto for any flavor of SS. Adapter plates are allowed. You can bolt up a trans that's not designed for your bellhousing.


If you are allowed to drop a motor from a '60s station wagon into the "trunk" of a Cobalt, why can't you bolt an auto to a stick only engine like a '70 BOSS 302 Mustang? In one, you rebuild the entire car. In the second you change the trans/bellhousing.

Except when you try to put that Boss 302 in a different body to run GT, it only gives you stick class
Stick only engine combos are only allowed to run in a stick class. Same goes for the 85 mustang carb 302.
