The Motown LS Hybrid never gained a lot of popularity but it does make a lot of power. Maybe more power than an LS motor with the same heads. The dyno sheet is from a 13.5:1 motor which would make a good E85 power plant. Knock it down to pump gas and it will still be 785hp or so. It is using Brodix BR7 heads which are medium priced custom heads when compared to All Pro's, LSR's, etc.
The engine is $12.9k from Ohio Crankshaft. An LS motor at that power level would be $20k or better. This engine makes sense if you have a lot of SBC stuff like a billet serpentine assy, etc.
Ive put up a lot of motors lately, only to show that there is a lot of good stuff out there. Ive never badmouthed an LS and think they are great. I wanted to show examples that an LS is not the only way to make good horsepower!
My primary interest is in engines. Everyone has a passion, lol.
