So you want 2 go Big block...Read this first!

I was saying with ALL things being equal,Starting with a /6 car,7 1/4 and drums on all 4 corners,That the cost to build a sb or bb are roughly going to be the same.In order to have a good reliable car you are gonna need about the same parts.From radiator to rearends.Both will probably need intake-carb,a good set of brakes,and a solid rear.Because even a fair sb can kill a 7 1/4 in no time.And it may be different there but good sb are goin for about the same prices as a bb around these parts.Agreed the main difference is exhaust,Headers vs stock manifolds....Rebuild kits are not that far away in costs,etc....etc....
