For sale is an 80s Chevy 5.7L 350 4-bolt main block set up for a 388 stroker combination. The block is .060" over and has been stroke clearanced. I originally bought it with plans to put it in my airboat, but my plans changed.
The machine shop recently bored and honed the block, decked it, stroke clearanced it, installed new cam bearings and freeze plugs, and thoroughly cleaned it. The only thing I’ve done since getting it back is paint it.
Great foundation for a 388 SBC stroker build. Block is ready for assembly.
