We finally hit the rollers today with our new 8.0Liter LS7 Package
LG Motorsports G8x4 ported heads
G8X4 cam
K&N Intake
Stock non ported Intake manifold and TB
8.0L endurance prepped shortblock
Prototype 2" Long tubes
Full 3" corsa catback
3.73 gears
Exedy Triple Carbon clutch
This thing is a monster! 500 rwtq from the hit at 3k! 
Talk about having your cake and eating it too! Making big power and retaining NICE drivability just became that much easier :thumbs:I will update this thread as we progress, I expect in the next few days we will near 675 rwhp, and potentially more
Louis
thanks.

I visited Louis at the shop yesterday. It's truly a legit build for one for all the nay-sayers. And I hope they get that bigger TB on there today for some new results. I only heard it run from start up to about 5K rpms since they were retrofitting an older TB on to a new style harness. Good job man. Nice to see ya yesterday too. You've grown a little in size since I last saw you several years ago. Ive added a few gray hairs myself..LOL

A larger tb (100+ mm's) should add a good 10+ rwhp and even more torque if you use my lgm built 402 as an example of a larger cubed motor going from a 90 to 95mm tb that gained 7 rwhp and 17 rwtq. The 488 should gain even more I would think. We'll see.
How about an update Louis.

Update time? What size TB is going on a 100MM? Have you tested the intake for a restriction? Do you think a sheetmetal intake would pick up any? That is the most power I have ever heard of through an ls7 intake just wondering when the intake maxes out? It must be maxed out here. I bet the ls7 intake would have better power under the curve with the 100mm TB compared to say a beck sheetmetal intake? Agree?
