whats this whole thing going to cost? i have a 350 that i want to rebuild. i may/may not (not decided yet) if im going to rebuild the stock 350 heads. im going to have to swap alot of things out to make it work. how much are fuel injectors, fuel pump, prom chip, and anything else i may need for the basic swap. i already have headers/3" exhuast that are installed with my 305, they should work great with a 350. i'm just trying to get an idea of what this whole project will cost. what does rebuilding an engine usually cost? then add the cost of all additional components to the cost. would i be able to sell the 305 or anything else to help recover the cost. its a 305 TBI high millage but runs good.
