Anybody have any suggestions for this?
I have a LHD 93 RX7 roller that is already Manual, I have a 2012 Caprice that I am thinking of pulling the motor out of its a 6.0 LS2/L77 (e85) with 106k on the motor. The engine is easily Boostable from either standpoint, though I would prefer the Twin Turbo compared to the LSA Supercharger (everyone seems to have that.) I was thinking of just using the Police Pursuit Auto Trans with a Shift box and steering wheel toggles, because that big *** police car is Fast AF auto or not. And in Pursuit mode it's even more ridiculous. I have a complete donor driveline setup (eng,trans,Diff &Axles) and have something actually unique in a super lightweight body.

After i fixed it, but i have to get the rebuilt title, otherwise use it for RX7
