Re: New Holley intakeat SEMA

I would definitely have added it to my "10x the tork, take too" test, if my motor hadn't given up. Someone else will have to take over, though. IDK if it'd do any better than the HSR, but I'd try it if I had a motor to try it on, still. The "repair" will be a 400, so not comparable, unfortunately.

Yeah? Is that true? "Significantly less"? "A good bit"? "Wipes the FLOOR!" What's that even mean??? We got the king of hyperbole and rhetoric, here! The Gen 3 6.0 makes about 300 lbs at 1000 RPM





What's the (larger 6.2L), w/VVT doing at 1k? STOCK?
