I found a complete sbc 400 in the junkyard. I am only interested in the block in order to start building a new short block for the Impala to put some real boost through. It rotates freely, but since it's untouched, I don't know what shape it is in. I can get the block for $75, the short block for $175.
It's a casting number '817' 400 4 bbl, 175 hp. Suffix code is CSX. Two bolt block.
My plan would be to slowly put it together as funds came along. Short fill the block, machine it for splayed four bolt main caps, get a forged crank, rods, and about 8.5:1 pistons. Either build it as a 406" or 420".
I know the 509 two bolt blocks are good, but don't know about these.
