Well here's #1 test, later I'll just add others here. A rumor going around is boss 429 a 6.3 bored and stroked, but idk, mpg standards. Too bad though a 777 would be nice to go vs 392/426 hemi and 427 lsx. On to the testing...

Truthfully 1/4 mi is plenty good. I was hoping a 1.1 g and like extra 3mph through cones. The gt500 out does it. They must of got told no out handling the gt500, Carroll said so and put shitty tires on it. With that price should have 2 sets of tires reg good summer and then like real track tires. I did see you could buy one w a a plan @ 35k. That would be ok for sure. Some are asking what about d and x plan. D w be like 36k, x prob 37k.

Some Laguna Seca footage. Sounds nice. Motor trend.
Found out 2 different tires p zero reg and p zero system for the ls boss 302
Now a r8 is pretty damn good track car, it smoked a zr1 on top gear but that was their track... Take the ls boss to the ring hide some nitrous under intake cowl. It could then hit some high speeds. boss 302 reg vs m3 vs r8 times. That tq curve is almost flat as a 03 cobra w a pulley.
