I'll wait until Chevy makes that 800 hp 'e-COPO' motor that bolts right in where an LS motor was.
Thats been available for a while, the e-copo was not the first... I personally built that motor. Also the motors for the Genovation GXE, LS platform Z06's, and the E-Cobra Jet. All of those motors came across my bench.

We design, manufacture, and support a pretty good array of motors, inverters, gearboxes, couplings, and are coming out with battery modules and BMS/Charging systems in the next year or so. I'm just the motor and gearbox assembly guy, but I have personally built and tested every motor and gearbox that has left our facility over the last 4 years.
There's a "EV Bot" calculator on our website. Our GM was the head of BorgWarner's Turbo division and the lead on the EFR project lineup, including the E--Turbo EFR series. So naturally he likes to give user configuration tools out to the masses to aid in getting the right thing to the right person.
If custom parts, adapters, bellhousing plates are needed, our sales team can help putting things into perspective.
