I have a 331 shortblock that is ready for assembly. It has a Eagle forged rotating assembly with H-beam rods and SRP dished pistons This is the internal balance rotating assembly they offer. Also comes with a main girdle. BB&T racing out of South Haven Mississippi did the machining on the block. Looking for $2000 and can meet if it's somewhat local. That's not rust in the first picture, I had the pistons in with some oil on the cylinder walls at the time. It's just some discoloration. The block and crank have been sprayed down and wrapped up for the last few years.
