there is a vid floating around on youtube, but it is not the best. I have been meaning to get sound clips of mine, but just have not had the time. We are doing a car show this weekend. I will try to get clips then and get them posted monday!

Thanks!

well this guy puts better heads and cam on his and is 30 under you 2... seems REAL crazy... any track numbers, id really like to know what a LS6 cam in a 5.3 would run in an otherwise stock ecsb 4x4 would run... cause id swap to a ls6 cam in a heartbeat if itd get my truck in the mid 14s with just cam and custom tune(have cold air kit & magnaflow exhaust installed, electric fans on the shelf)

Dyno numbers can be very misleading. Different setups, different dynos, different methods of smoothing, etc. Even sea level corrected track times are varied. Different tracks, different surfaces, different means of putting power to the ground (trans, gear, tire). No accurate comparison can be made unless done in the exact same means, ie same dyno or same track on the same raceday....

RWHP numbers for this truck can be improved with the addition of electric fans. Also, everyone needs to realize these are a "Stage 1" head, with stock LS1 sized valves and light porting. They are not milled for compression and as such, will rob some torque; and horsepower, as most know, is a mathematical calcuation derived from tq. Also, compression comes out to about 9.5:1 on this setup (same as stock). With a milled .030" head, it would bump it to around 10.5:1 and would produce also better numbers. This is something I may look at in the future, but since I daily drive this truck and use it as truck hauling quads, and a car hauler regularly. I did not want to run the risk of detenation. Therefore, the 86 octane friendly 9.5:1 CR was opted for.

As soon as I get around to installing E-Fans, I will put the truck back on the SAME dyno and see what results we get.
