Magnacharger (Eaton), KenneBell, and Whipple all make a roots blower for the LS engines.
The TVS 2300 has made the numbers he is after on pump gas with a forged 6.0 block. With the newer Whipple 4.0 blower those numbers will be really easy to get.
The Magnachargers are the best priced for what you get IMO.
Then you also have the centri blowers like the paxton, vortec, and pro charger. I personally like the procharger. In fact the 2 fastest stock rotating assembly SS Silverados In the country are D1 procharged both with stock heads.. They are running 11.0X 1/4 and weigh in at 5200+ lbs.
Turbos are cool but a total pain in the ***** to tune and get running right unless it is a full out race effort, but on a budget the blowers just down right work!
