5 of 5 385 sbc stroker block November 27, 2017
Reviewer: Michael Wester from Rociada, NM United States  
Super good shipping container, wooden oem crate with anti rust blanket and anti rust containment bag. Machine work is first rate, very clean block and oil passages, brass freeze plugs, and a heavy coat of paint. Cam bushing installed and line bore checked excellent, squared up block deck and lifter bores smooth. I am a 50 year + automotive machinist and it passes all my specs.
