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

I dont know but i think the costare just about = for BB or SB!Well if you go BB its because you want power.So you figure in the cost to make a SB put out like a BB then it all starts to even out.And a good route to go is to start with a donor C body.And if you build a good SB you need a good radiator also.
Then saying its a BB when anyone asks=PRICELESS
