This is a copy of the dyno test of my stock LS6. Its a beast. lots of torque off idle. The engine guy said he would get 50 more hp with a higher intake. gary

Cool Gary, very stout :thumbsup:

Something going on there. A sag in the torque curve at 3700 and again at 4400. The hp levels off at 5300. I think that there is more in this engine yet. It would be interesting to see if the high rise older intake would make much difference.
