Yes this drivetrain will fit easy same with the current caddy 4.6l and the 4.0 aurora. both have a ton of performance options. It is hard to come by people who have mapped the computer that much. this is why some guy put a engine in the trunk on top of the stock drivetrain up front of his caddy for a 600hp Awd caddy. Yes it is true. Ill find the link. So there is a reason he did this and it was the computer. Now I have a solution but that is my secret and until I get the money to put the kit to work I will have to keep that part a secret. Now if I find a buyer then I will make the kit for them at cost just to flex the option. I have a local shop that can do it starting last year. LOL
I can also do a rwd Bonneville fairly cheap but it depends on the cost of donor parts. I am not just joking either I can and will back up my talk with action.
I am only handicapped by my past divorce from my ex and money.
So until I get back on my feet the car is a subject only.
