Would a carb kit or a TBI kit be used? Would any fabrication be necessary?

 

The NOS kit number 5153 requires no mod except for cutting the stainless fuel line to tap into for fuel. Its a straightforward design and all designed for the TBI (the plate that is ) and has a 50 100 and 125 jet kit included.
Mine took a half second off the 1/4 on an ice cold bottle so a heater should do better

 

it wouldnt work with any setup that bolted between the manifold and tbi because there is no place to put a plate in there on mine. i could figure something out though.
