There is a guy that did an excellent swap into his 1965 El Camino, looks like a factory 1995 under the hood.
He used the tank and everything. I decided to get the FiTech setup based on his idea to use the Roadmaster tank and factory fuel pump. (no, I still haven't put it in yet, other projects...)
I had a 1994 LT1 Caprice LS, and would LOVE that setup in my El Camino. Tons of torque for factory setup, would get 30mpg on the highway at 70MPH.
Yep, a quick way to tell is all the 5.7 LT1 B bodies got dual exhaust, the 4.3 got a single.If you get a LT type engine from an Impala be aware that there was a 4.3 L V-8 engine that looked externally like the 5.7 L V-8 engine.
