I have read quite a bit but still gathering info. My 67 coupe is a auto and after considering the T5 swap Im looking alot more at the 4 speed auto. Other than the controller I could probably come out cheaper with the auto unless I go crazy with all custom stuff. I have had sticks for ever and just looking at a different idea. Anyways I know V6 engines have the same bolt pattern as a Windsor and Im planning on 351. I also read years 2000 and above are improved and a better product so Im just looking for knowledge and input.
