The Z/28 and ZL1 are very different cars from the weight to suspension to RWHP. The ZL1 is power dependent. The Z/28 is momentum dependent. The Z/28 brakes later, carries higher speed into the corners, mid-corner and exit speed. The Z/28 runs out of power on the straights. Drop a built LS7 into the Z/28 ad it will be amazing on the ring. I spoke with some GM people related to the project asking if they couldn't find a heads, cam and tune package in-house for the next run at the Ring...
You can add all the RWHP you want to either version of the Camaro Z. Anything over 630 at the rear wheels is unusable on a road course with a 305. The Z/28 is overbuilt for 505 at the crank. The weight, lower CG, brakes and aero on the Z/28 are a huge advantage to the Z/28. A pulley and tune get the ZL1 close to the ideal RWHP number, but weight, the location of the weight, and CG work against it.

Didn't mean to imply both cars would be the same. Indeed they are very different animals. I just get an allergic reaction to folks saying one is faster by 3 seconds without taking tires into consideration. Kinda like "cheating" in my book anyway.
And I am exstatic with your mention of extra power for the Z28. Now we are talking! Get it close to 600, yet NA, and it will be worth every penny and nothing comparable will touch it. It is more difficult to drive a monentum car IMO. Takes a lot more skill from a driver. An average folk will be slow (without the extra power). Unless they switched from a Bimmer
Good posts and very informative - thank you!
