I hope you are right, your numbers are very nice.

 

I dount doubt it for a second. Keep your top end stock CR and try to dyno tune on a cooler day! I can feel a big difference betreen 75* and 90*

 

Anyone know the part numbers for the 918 springs?

Nevermind I found them.

Are they really worth double the money of the LS6 Springs?

 

PART #26918-16

O.D.: 1.055/1.290
I.D.: 0.650/0.885
Seat Load: 130@ 1.800

TitaniumRetainer: 772,762
SteelRetainer: 774,783,761,787

i believe these are the right ones.

 

Thanks, i found them too.

What all will I need
Cam
Springs
Pushrods
Timing Chain

What else, or is all that even necessary. Are the 918s really that much better than LS6

 

I dont think you need the timing chain. I'm running stock on my Tuner's advice, and he knows his LSx's.

 

Alright, what about an upgraded oil pump

 

If you need help let me know I did mine I would be glad to show you problem spot to save time. Oh and i have the crane spring install tool you can use and the air hose for the cylinders just have to find them.

 

nice numbers there dub...

 

nice numbers there!
