<div class='quotetop'>QUOTE(Red03SilSS @ Jan 19 2007, 11:56 AM) [snapback]80387[/snapback]</div>You will get the most out of a cam if you do the stall at the same time. So it would have to be Cam and Stall.[/b]Definitely. If it were my truck I would get a shift kit & converter pronto - not only will you improve tranny life but also knock another .3-.4 secs off your 1/4-mile time. Shift kits are $200-250, the Trailblazer 6-cyl converter stalls at about 2400-rpm and can be purchased for $100, but the TCC clutch is too weak to tow so if you want high stall and towing in overdrive then get a good aftermarket converter but that will chew into your budget, the better ones are $800-900. After that I would look at a cam, maybe something along the line of a Comp 273 but again I don't know how big your motor is so that might be a step too large; for comparable prices you can also look at FMS, or have NP spec you a cam he knows will work well in your truck.
Eliminating cats typically only gains .1-sec in 1/4-mile (assuming you already have headers and true dual catback). But if you really have no problem with this then have NP disable the rear O2 sensors in your tune and you're good to go.
If you spend your budget on headers & exhaust that will eat-up almost all your funds, and I would suggest these mods first -That's $1100-1200 in mods. Of course you would have to do your own wrenching.
- Shift Kit (Superior, $200-250)
- TB converter (Dayco, $100-125)
- Gut converters ($20)
- CAI ($250)
- NP tune ($500)
After that - well it's kind of a toss-up. An aftermarket cam & springs will set you back an additional $500-600, and Pacesetters cost a little more than that but occasionally these do pop-up used in the forum want-ads. I would probably do the longtubes & exhaust first, cam/springs last but ultimately you will want both. And a re-tune!
My 2-cents...
