L!1 in a vette
I have the LS1 - basically stock in my 99 coupe - 6 sp, 3.73 rear, better intake, exhaust and brakes. I think the L! series are the best SBC ever built - can drive at 650 rpm in 6th gear, never lugs - thus really fantastic mileage. Must be mostly due to SFI. Many major changes from past 350 SBC, even different firing order.
