Grabbed this off of corvette forum. No idea on accuracy. Claiming an LT7 is in the works, FPC NA

Flat plane crank doesn't make sense in an OHV engine. The valve train won't be stable enough to take advantage of the rev capability.
Edit: This could be a Cadillac specific engine and move to a DOHC engine. GM has already said a DTC system that could handle the torque of the LT4 would be too heavy. They already have the 8 speed auto and have been working on 9 and 10 speeds with Ford.

I find it suspicious that Ford grabbed international auto headlines with the 5.2 FPC and now someone is claiming that GM is also.
Seems like a desperate "me too! me too!" |

it's not that simple. they would have change the compression ratio, camshaft profiles, etc. it would be a new motor. they would probably stick with hypereutectic pistons in a n/a motor as well as they have a more optimum thermal expansion coefficient and you don't need a forged piston in that power range at all. you pull the blower off and lt4 and you probably just have a 400-425hp motor. my ls7 lasted perfectly for 5 years but I was stock. I did inspect the valve train geometry based on the paranoia around the platform though.

For the money the Gen 5 Camaro Z28 is underpowered. That car is in dire need of 625 hp.
