Actually, it is really incredible how far advanced this ZR1 was for the time.
Amazing.
I wonder what GM would have been able to do with the DOHC motor if they continued with it.

^^ There was a local guy near me with a black ZR1 way back when. He had the LT5 built. Had aftermarket cams, Ported intake, Full exhaust, and I can't remember what else. But the sound it made, was AWESOME! Most everyone was scared to run him at the time. Just a Radical car!

415ci LT5 normally aspirated by these guys can yield 673hp. This is what the C7 ZR1 should be running.

I'm sure they could have done wonders but it would not have helped sales enough at the time to make it wise. Ford, Dodge, GM, or any other manufacturer can get the technology from various race teams and or other engineers from other manufacturers. There really aren't many secrets or loyalty in the business world. Most of the bad decisions made are by bean counters, not the folks with performance passion.

It would have not been because of a performance difference since LS motors make great power for their size but more to distinguish the Vette from the Camaro line and do more experimentation with a DOHC motor in terms of a small displacement, high rpms and FI.
Just saying, it could have been a selling point.

With stock LS1 and LS6 heads HiHo and Ballpien Hammer.
We have two head cam LT5s here at work with extrude honed intakes owned by employees. In cool air they have gone high 10s on drag radials. There is a white one running around converted to auto with exhaust and tune that runs high 11s at 117.

Dont quote me 100% but i remember reading an old article way back in the day( i forgot what magazine) but when gm tested and compared the chevy dohc vs the ohv motor at the time everyone chose to go with the ohv as it was faster and the instant torque.
