My mom says thanks for the pearl necklace.
Ecam...that says alot about the issue..especially with an AOD..change out the cam for stocker...or better suited cam. You could try degreeing the cam 4 degrees advanced..may brring up the bottom end a bit. Ecam is a turtle before three thousand rpm generally.

3000 rpm is where the cam starts to make power. I use the Ecam (not for much longer) and if I take off in second gear and hold it to the floor it is dead untill it sweeps through 3000, more like 3200 actually, then it will start to spin tires and race to readline.
When your friend was using the 3000 stall where did it rev to with the brake on?
Maybe he had a "tight" converter
? I would have thought it should have been enough. However I would re degree the cam an try advancing it, as was suggested by DMAN302, this should start the cam making power a little sooner.
Good luck.

my e303 cam makes great lowend power, not to mention it pulls like a mofo all the way to 5500+
granted, if i were teh one to have put the cam in, i would not have gotten teh e-cam

I agree that the Ecam has good top end power, I get the best results shifting at 5800rpm, however if you start off in second gear (stick) you will notice a huge acceleration "boost" at around 3000rpm where the cam starts its power range. This is why it feels like a "dog" before that. This lack of power does not seem to be as noticeable with the standard having a 3.35 first gear, but can seem like forever in a auto with a converter that will not allow the engine up into this power range.super302 said:my e303 cam makes great lowend power, not to mention it pulls like a mofo all the way to 5500+

Great... advancing the cam was the trick!! It is always better to work with what you have , than dump money into something blindly!! We have had killer results with the E cam in as far as 6* advanced!! and AOD's !! Have fun....
