Sounds good but from what I hear it doesn't lope as good as the gt9 cam videos in a 6.2l ls3. I want alittle more lope. I think the 427 displacement smoothes out the cam.

Cool, Mine didn't get lost either, it is just really quiet after coming through the turbo's.. If I installed cutouts it would sound wicked...

I'll see if I can get a video and post it up...

It isn't the cubes that smooth it, it's the LSA... Narrow the LSA and the rump rump comes in.... That isn't the best choice for a FI motor though... NA, go for a really narrow LSA and it'll shake and rump all you want...

Here is the video of my GT9 Lingenfelter cam in my LS-3 Stroker 427 with Twin Turbos... This cam has a 121 degree LSA...With the twin turbo's, this is on the stock manifolds. The turbo's bolt directly to the manifolds... The down pipes coming off the turbos are three inch as is the entire system from there...There is ZERO drone with this set-up....

Yours will sound even better with the long tubes... They say turbos are the best mufflers ever made, chopping the sounds waves up into a million lil pieces.... can't wait to hear yours...
