1400HP on a stock shortblock?

I'm going to be realistic and say you better have a sleeved block, with a billet crank and steel caps and studs and even with all that life of engine measured in hours not days or years.

Since the ZR1 is dual inject, I'm going to assume at this time next year all builds will be dual inject using a GM brain and wire harness.

ZR1 has a different ECU and there would be compatibility issues using the GM setup. Per Ben @ Weapon X.

Note the "wire harness" and "next" year; GM comes out all the time with programmable ecus, and the after market will deliver one too.

I'm pretty sure that is not a stock short block.

Yeah, that means the ZR1 supercharger has port injection bungs. I kind of agree that a resourceful person should be able to figure out a "GM" duel injection system once these parts are readily available. In theory the LT5 supercharger swap could be the bomb for HP nuts. Still waiting for all of this stuff to filter out to the public though.

World works with positive thinking. IMO factory support is key to get parts into the race car.
