Just wondering about some fan's i have dug up on ebay. I know the ls1/lt1 fans seem to be the goin rate I found another fan for cheaper. its a single tho, but says it does 5000 cfm. Just wondering if that would be plenty for my 4.8, or better off with a dual set-up? How bout a 6L or turbo in the 4.8? Just thinking about things I might want to do in the future and dont want to do it twice.

thanks
