I have an 03 Chevy 5.3 EC with mods that include (and/or will include), true duals w/magnaflows and QTEC's, K&N FIPK, vigilante verter, 2800 stall, mild comp cam, and throttle body spacer. What kind of numbers should I see when I dyno it three weeks from now? What others mods should I consider for now? What kind of 1/4 mile times might I see?

 

By the way the cam numbers are 212/218 .522/.529 114.

 

Do you have any kind of tune? If not you are probably gonna want with that cam to get the most out of it.. What gears are you running? Posi?

 

3.73 gears and the tune will be on the dyno.

 

Come on people I just want a ballpark figure!!!!!!!!!!!!!!!
I want to be somewhere close to 300.

 

i'm guessing in the 280-290 range. prolly run about a 14.5 give or take in the 1/4 mile.

 

i think you will be close to 300hp.

 

Just guessing, but I'm pretty sure you will be below 300. I'd say somewhere in the 270-285 range. Maybe a little higher. You should be squarely in the 14's with this setup.

 

Thanx any suggestions from here?

 

Well, you can ditch the throttle body spacer, its a paper weight. You have the converter, are you using a transgo shift kit, and vette or billet servos, if not, get the set/kit. This will allow you to remove your torque management and change your downshifts. Get that tune in with the cam. Really, the big reason you might see the power that you will is the cam. Get some headers, and a set of electric fans.

I put out 279 hp to the wheels with the mods in my sig, not headers/ no cam, at least not yet, headers soon to come. What rear end you running, gears? Locker or posi or LSD? and you might want to add a trans cooler.
