Vette as "benchmark":

Z06 @ 3199 Curb = 7:22 @ the 'Ring (-133 "rated" hp)

ZR1 @ 3353 Curb = 7:19 @ the 'Ring (+154 "rated" lb.)

I believe you'll find a greater weight difference between a ZL1 and a "wet" LS7'd ZEE, but NOT as much hp. differential...

Whether equipped with a lower weight-optimized MR, or a BOSS-type "mechanical-only" weight-conscious suspension (non-MR), with 305s fr-rr, a ZEE could be a match (or veryvery close) for the ZL1...just as the BOSS, minus 100+ hp, is to the GT 500 at places like VIR...

It's one thing to have gi-normous power but, as the Vette shows/proves, it's another thing altogether to use that power effectively at all times.

And, as good as MR may be, it's not likely to harness almost 600 hp in 4100 lbs effectively at all times...it doesn't in the 3353 lb. ZR1...

IF the ZL1 is street-ready @ 4100 lbs, with 580 hp, that = 7.07 lb/hp. For an LS7 weighing 3850 lb (1SS Curb), 7.07 = 545 hp...NOT "impossible"...

As to the PEDDERS et al ZEE-something, some serious power is capable, at a significant weight-savings, with a massaged LS7...or WARHAWK...well beyond the LSA's "rated" 580/556...without the added mass of FI... 2 or 300 lb. on a road course car is mammoth weight to carry...and very significant to delete...

I suspect what's coming for SEMA is NOT hampered by GM's production viability constraints. Weight-savings that Oshawa will not have to worry about will be included. And the power-to-weight will dwarf the ZL1...as will its performance capabilities...
