The only good corvette engine was the LT5 in the C4 ZR1, all aluminum high comp DOHC V8 engineered partially by lotus. They showed GM the way, and GM went right back to ancient shit because they're cheap. Except for the northstar, which as we all know is the true powerhouse of GM engines.
side note: fuck the H button on this shitty keyboard.
Go ahead and describe this "exact same motor".
Better yet, make it lighter than the LS7 (good luck with 3 more cams and twice the valves), keep the CG low, keep it compact to fit between the Vette's suspension, make more power and get the same gas mileage (sorry BMW M3 and GT3). And you already addressed the cost issue.
Sorry, but the LSx series of motors will shit all over your theoretical DOHC all day in those categories.
