Running into some probs though.... I got no power under 3000rpm. It barely moves itself until then but over 3k it blows the tires away. I did restall the converter to 2800-3200. It seams the engine is the one with the problem though. Also posted on ls1tech. I tried swapping o2 sensor plugs from side to side. No luck. Anybody got any ideas?

Did you find that with the Dirty Dingo mounts and the factory a/c position that the drag link came way to close to the oil pan and harness? I ended up removing the a/c and moving the whole eng/trans back to gain clearance on my LS install. Did you have to do the same?

I pulled the dirty dingos and swapped for moroso because of the schnoenfeld headers. Too close to drglink as you stated. Moroso worked better for me

Thanks, did you relocate/remove the a/c and did you have to relocate the starter wiring? Got any pics of the Moroso set up? Good looking build so far.
