I'm not sure on what year 350 engine to get for my 84' el camino. It currently has a 305 with 350 heads on it and a bunch of wires that i want to get rid of. I plan on using some of the accessories off the engine thats already in there. The only upgrades im going to put on the engine for the mean time are just air gap intake, 650 carb, headers, hydraulic cam, lifters and pushrods. And I want to get rid of the fan so do i just change the fan clutch to a belt setup?
