1. They do build engines like that, but the weight isn't comparable with aircraft engine when you factor in gear box, radiator etc. The Ecotec platform produces a better hp/weight ratio than an aircraft engine in most cases. 320lbs is what the 122ci (2.0L) engine weighs. Factor in a 65lb gear box and a little more for radiator and it's right near 400lbs. Engine puts out 1hp/lb in it's final configuration. Hard to match that in a reliable package 2. Belt drives are typically not lighter
My mission is to build my own plane with an automotive power plant for which I will probably need a reduction gearbox, 1. Why can't someone build a high Torque low RPM V-8 to match an airplane engine a Stroked 350 or 500 + C.U. motor R.V. cam with peak output at 3000 RPM. 2. I realize there are torsional effects and tremendous forces at work but couldn't one just use a massive belt and oversize the bearings ? It's just a transmission they had them in WW2 it shouldn't be that hard.

What is the engine power?

Did you go into production with the final gear box?
Is that the LNF engine or ltg? Where did you get a wiring harness for it?
Is there any way to adjust a gear box to help reduce the play in the gears?
What ratio are you running?

davetileguy they already have built an LS engine for aircraft use and it passed the 2000 hour tbo requirements as well as other testing.
