I think those numbers are really good for a 226 cam, A4, and 3.73 gears. I'll upgrade really good to "damn good" if those numbers were with the cats in place. Were you running thru the cats?

Nice numbers! I got 405/385 with mods in sig. And the H/C cost me under $1000 including install. I ran a 13.4@107 with a 2.2 60ft before the H/C. I sure hope I can break into he 12's tomorrow.

Hey guys , we just got back, Car is awesome! Numbers are a tad higher then Mikey said before. 403.8 and 381.3. So you guys think high 10's?
I have the dyno chart, and i tried to attach it but it says file too big? Its 242 and it says max is 100

btw.. mail me the graph to sculbert1@netzero.net and I'll host it when I get to work in the morning.
Not to bash but 405 rwhp with stage 2 heads and a cam that still has a nice lift to it seems kinda low to me.I would say it was awesome on stock heads but i think you should be above 405 with that setup. 
destroyer look over all the other auto's that are out there few ever even reach 400...there are the occasional "freaks" but most head/cam combos hover around 400-420...i think his #'s are pretty darn good for a low budget combo

That is why I said with the right gear, suspension and traction he'll hit it
I would guess 11.3@120mph unlocked with stock rear gears on ET street and 3500 stall at 3500-3600 pounds
