Nothing against it,To each their own . Just for each intended use there is a combination that fits . I didn't want to add clutter under my hood so I went solid roller with cubic inches. A small shot of nitrous when I want more.
My car is a cruiser and my kids ride in it so no roll bar, already makes more power than I can use at the track with out being run off so a turbo or blower wasnt needed to reach my goals.
Next one will be built for the power it has and be able to use it. Turbo will be used for that build.

I have quite a number of friends who roll with f/i C6 vettes here in town, but none of them run HPDE's, nor do they push there cars in the heat of summer in the desert southwest....it's a whole different story there.
A sub 3000 lbs N/A car putting 600-700 RWHP in N/A form can be a handful to drive, and drivability can most certainly suffer is some of the more extreme configurations, but a deep breathing, high winding LS is my cup of tea....especially if you're road racing too.

If you get compression up ...with higher lifts and the ability to supply what's observed with the intake on...as seen without it = Hp. not rpm dependant. Rpm is hp but can be achieved at lower rpm with this train of thought

That's what ****'$ me off...why do a shorter stroke? Crank size and rpm go hand and foot. The high rpm build for the guy in the optima street challenge with the z06 and 388 ci...Hammer?
Forgot the owners name.but he
Took his dumb as back to a larger 440 with the same high rpm. Not that he's dumb but .....$ to Blow
No Replacement for Displacement.
Wish my block had a 4.200 bore & the same 4 inch bottom end. Bigger port needed then...more $

I know it's not Hammer... The guy competes in the SEMA optima street challenge event with a c5 Zo6. Willing to bet this is where Hammer got the idea for a 388. Now a 440 with 8k+ rpm for last yrs event. Hadn't worked it all out yet but 650+ to the rear with minimal testing.

Danny can flat drive. I’ve followed him for several years and the dude can wheel a car around a course like nobody else. Crazy car control. That 388 he runs doesn’t make a ton of power, but you don’t need big power to go fast in the stuff he does. Driver skillz far outweigh what’s under the hood.

Class, especially since he won the National 2018 Optima Challenge, and the LSFest
Competitions as well in his 2007 C6 Z06. Been going head to head with Danny for
several years now.
Totally agree with you Dan! I was actually glad to see Danny get some pressure in the class.

Same here: Dwill's 408 with 820 hp on a low reading dyno...
Or John B. 427 Ls7 = a Jr version...even had Darin make me a Ls7 head 1 of 1 also.
Later set up = 800+lift and min.14.5 comp 98% street....kinda sounds like John with street use?
