When I purchased my El Camino, the builder had installed a Tuned Port fuel injection. It ran fine but had a sluggish mid range. I decided to update to a Holley Sniper. Finished it up after a couple weeks. I dropped the custom stainless tank, put a new higher psi pump in, new Wieand single plane intake, new Accel distributor, Lokar bracket for my existing throttle and kick down cables, and a bunch of other things need for the conversion. So far, I like it, but I am waiting for my air cleaner to arrive before I do much driving.
