And with electronic throttle, it's going to be better anyway because throttle tip-in is more progressive and measured and controlled. Just my experience owning a GTO and driving a few muscle cars.
I wouldn't want a carbed car. If I built a muscle car, I'd put an LS motor in it.
+1 I'm running about 800 hp/676 rwhp wiht a S/C of course but all due to A/F calibrations and a nice monoblade throttle body I'm able to get 20mpg+ on the hiway, and run 10 sec 1/4 miles.. Thats technology
