highly considering ditching the tbi and going with a traditional carb setup. did previous 4.1 offer a carb setup and if so what year intake manifolds will fit the 87 ht4100 without alot of needless fabbing. ill leave the electronic in for the fuel and climate controls but all other bs emission will be removed and a carb added any help with this one?

and just for future notes any other engines swap common with the fwd deville besides the 4100,4.5 and 4.9? prefer a 305,307,350 heck even a 3800 series would be fine. transmissions i suppose may bolt up or any ideas there?
