Good luck! Good numbers with ported LS6 heads!

Do you have the LS1 intake, or LS6. If you have the LS1 you should pick up around 22 rwhp. If you have the LS6 intake, you should see 17 rwhp. I would expect these numbers maybe a couple more. Tony Mamo says going from stock LS1 intake and 78 unported TB to his custom ported 90/90 you could see up 27 rwhp. Good luck!!!
