'Budget' 340 build suggestions

if your running a 800cfm carb your going to need an updated cam for sure to have a longer intake duration but if your going through the trouble of having the engine cleaned and bored you might as well get a stroker kit or a rebuild kit they're going to cost around the same or you can go on e bay fin a used crank pistons and connecting rods and other various parts for the cylinder heads but that also is going to be at least over $1000

hope that helped
