A833 NP A body trans ID help & intro.

Ahhhhhh, it ain’t that bad, unlike the ... 3.09 first gear of the OD box. I’d like to find one of those 2.66 - 1 gear transmissions.
Well I wont feel it for long. I will be pulling the 318 & 3 speed trans and preserving it, as the Twister is all original, interior and Paint. In a couple months I'll be looking for a 360 71'-72' with the thicker cylinder walls. Will either build it strong or go with a 408 stroker kit. Gonna have me some fun!
