Powertrain Integration is using the 8.0l from GM. GM has made it available in crate form too. Part# 19328586. Power Solutions Intl has I'm assuming a modified version of the 8.0. Theirs is the 8.8l. Both have devised a plate system to mount accessories on the front of the engine. Makes hanging an air brake compressor simple. Cheaper gas has made gas attractive again esp with the EPA regs on diesel engines. Diesel engines are expensive and the latest emissions very expensive to service. Fleet owners don't need those surprises and downtime. Both of these outfits have LPG versions of this engine. Its kind of cool how whats old is new again.
