i am building my first v8 and am on a budjet. My uncle gave me a carter 4brl 650, carb. Ii wll put in on a stock cast iron 4brrl 289 manifold. cran energizer cam 272/480 lift. Ported heads with chev 305 h.o valves. it will be all knew inside except new crank and rods but it will be honed and maybe bored. It is a great running motor and it is a tight one so i am just trying to make it have as much performance with the budjet. and i will try to put flat top pistons in it also. anything helps thank.
