Hey, guys, sorry for the lapse of reason...
Anyway, I can't recall what the compression was and my numbers could be a little off, since it was almost 9 years ago. We changed-out so many different cams and rockers and such, that I'd have to call my buddy to remember. He's got it all written somewhere, as he runs a performance shop and he beefs-up alot of powerboats and racecars and trucks so he tends to file all the dyno/ build sheets. We originally started to build a 'Bummer' out of my truck, but then the company that made the fiberglass Hummer-replica was getting sued by GM when they took over the Hummer. So, we started messing with the engine, since we already had it torn apart.
As far as the catalyst, I don't see the point in talking about it, since nobody cares about it anyway. I don't get any money from them, so what do I care if anybody gets one?! I'll be getting one soon for my JK, because I know it worked for me. Every gain counts...
I already got my cold-air-intake, and I'll be sealing it off from the engine compartment and heat-shielding it too. Even though many people don't think they really make a difference, I'll keep trying to squeak every bit of power out of my engine. After the catalyst, I'm gonna try the TB spacer, even though it only makes a difference at low RPM it would still be nice to have a little more torque since I won't be changing my gears for at least a year or two... Then I'll be getting a reprogrammer, for the shift-points and speedo and power....
