yah for your first rebuild stick with small block chevys they are cheap, sturdy, easy to find and easy to make power with, you could buy a brand new GM performance crate 350 with something like 275? hp for half of what it will cost you to build that flathead, if you wanted more power you could a always buy a cam, headers, a decent intake and maybe some vortec heads and you still prob. wouldnt have spent as much as it will cost to build a flathead. yes flatheads are cool but they are expensive and basically outdated but still cool in an old hotrod
