I believe a franken LSx of a special sort would be the best idea ive had on 5 hours sleep. When i saw this on my way to a diner omelette by my hotel, i felt that respect heartbeat. Such solid cars. And a need to Eff it up into a track day bastard special.
So the idea? LS3 with a 4.8 short stroke crank. 3rd party heads and that makes 600hp at 8k rpm. Mmmmm. That was a good omelette.
You may now resume swimming.
