5.3 with an STS

We made 438/446 in an '05 Yukon. LS6 cam and springs, Walbro pump, 43lb injectors, fmic, GT-67, and 8psi. Dont know how much difference it makes on the dyno, but the truck has 24" wheels.

Very nice!!!! One more vehicle to watch out for on the road.
BTW, are you gonna be around June 20-25th? The Hemi Rally is coming to Arlington during this time and I was tempted to drop in for a day or two. Would love to come by your shop and check things out....

Those pulls were so rich, they were off the grid. The timing was 11 to 12 degrees from start to finish (0 knock retard). This truck is far from being "finish" tuned , but it's a pretty good starting point.

The Walbro is what we used and so far seems to be working great. We also did the 43lb injectors.
