Starting a buildup of an '99 LS1. Looking for descent street drivability and fuel mileage. Must be able to run on premium. Need suggestions for cam, heads. Using an LS6 intake or the Holley version of the LS6 intake. Help me build a killer street engine.

 

There's a couple ways to go about this. What kind of reliability are you looking for? Will this be a daily driver? What kind of gas mileage are you looking to get? Is this an A4/M6?

Give me a little bit more info and I can give you my two cents.
