you are adding over 150 rwhp (stock c6 z06’s typically dyno 440, the zr1 dynos 570… then you have to keep in account that the zr1 is 250 lbs lighter) to the z06 with heads and cam. If you think a cam that size is not going to have any cam surge, have a high rpm power band, won’t need steep gears, won’t have any driveability issues, you need to hang up your fuck stick corvette hat up and crash your car into a tree, and get back into dsm.
and if you are going for bang for your buck, yeah sorry, corvette was never on the top of the list if all you are comparing is straight line times.
and your ass will never own a zr1 because gm doesn’t offer an automatic transmission as an option
