Holland Automotive Machine is a reputable shop. I know the owner personally. They build regular engines and high performance engines across all brands. Stellar work. Please withhold the flaming- I have my reasons why I paid to have this done. 360 Magnum short block dropped off with all 300,000 miles of gunk and gak. They reused the stock crank and rods per my request. I supplied the Auto Tec forged pistons/moly rings, Howards roller cam, dampener, oil pump and oil pan. I'm porting a nice set of Magnum factory heads and a 144 Weiand street blower will top it off. REFERENCE only. Your costs WILL VARY.
