400 is the way to go for sbc. I look for the 509 blocks, most have 3 side freeze plugs, some have only 2 and look for 020 and 010 in the timing cover area, higher nickel content in the casting. Cant remember, but think the high nickel might also have squares in the lifter valley area too. I spend around 2k building a 408 with parts and machine work usually. Best bottom end kit that I like is around 1k from Skip White on ebay here http://www.ebay.com/itm/SBC-CHEVY-4...MJ-/351614440164?_trksid=p2385738.m2548.l4275
Gives you internal balance which is way better than old external balance when it comes to rpm.
