Hope I'm not adding my 2 cents too late about FI in the Elky. The '85-'88 Monte/'85-'87 Elky had 4.3 FI (LB4) for the base engine. Other G bodies that used the 4.3 in final years would also br FI. They all will have the in tank pumps. For better pressure, would a pump from a turbo Buick be usable on the LT1 swap?
