underdrive pulleys
just had a quick question about underdrive pulleys, do they really make the 15 horsepower that they claim? i just dyno'ed 284/327 and would like to have 300 hp. also, is there any specific brand that anyone would recommend.

I agree, you won't see anything really with them. Mostly they will reduce the amount of drag on the engine accessories. And possibly help with your electrical system. I wouldn't recommend them. Just my .02

15HP might be remotely possible on an engine with a belt driven water pump and a belt driven AIR pump..... your LT1 has neither.
