Who is running a modified LS1? Questions...

Its perfectly normal, especially after you install headers on an LS1. The valvetrains can get pretty noisy. The factory cast iron exhaust manifolds muffle most of that valvetrain noise, but headers seem to amplify it.

No biggie, turn up the radio :D

Now that's the info I was looking for! Thanks!

We drove the car about 200 miles today to Silver Springs and enjoyed pretended to be Tourists in our own backyard. Car ran perfect. A/c was cold (so cold my boy had goose bumps), cruise control was tight and right...and of course, the engine was sewing away under the hood. LOL.
