Default Where would you guys go from here

I bought my daughter a 54,000 mile 3.23 2000 z28 after selling her 76 cutlass that was 11.5 to 1 had 4.10 gears and a 3500 stall with dumped exhaust before rear axle with spin tech 9000 mufflers. So the new car is much more quiet, comfortable, and has AC and t tops she loves it. When we bought it my wife's Grand Cherokee would just pull this thing hard didn't matter dig or roll. We were a little disappointed it ran a 13.34 at 105 in 90 degree weather with high humidity, but the jeep went 12.78 at 105 the same day. Fast forward we have installed a BBK intake(came with car) ls6 pcv conversion with catch can, BBK long tubes, and catless y pipe, with a slp loud mouth II catback(still way quieter then cutlass). Replaced the maf meter which got rid of all spark knock which was bad over 4500rpm before switch. Got a yank ss4000 conv and a frost tune. Have not been to track but car will pull jeep everywhere now except dig, and pulls it hard at 20mph or 50 mph. Car would pull jeep even without convertor but does more so now, car has umi lowers with relocation brackets and a suncoast hood with there ram air setup. Now for the question what should we do next heads and combo like Texas speed 243 stage 2.5 kit or something else. Would like car to run 12.5's on drag radials, and still be driven everyday. Thanks for any help snow is coming soon here so need a project for winter.

Spray?H/C? Id spray it if she drives it everyday that way its still 100% street friendly and when you go to track you have the extra power on tap. Just an opinion

With the mods you have, just add drag radials and the car should run 12.5's all day every day.

3.73 or 3.90 gear would help it from a dig if you could hook it

I would get a wideband and see what the AFR is at. A mail order tune is just to get you in the range so that you can fine tune it on a dyno or the street.

I hope the car is in the 12's now also with the drag radial. We will be going back in a few weeks long as is it quits raining. temperature today is 61 degrees so it will be much cooler also. Traction is much different now with street tires and convertor, before convertor you could keep spinning to minimum but not now.

Tsp 2.5 5.3 heads and 224 cam will make a nice daily driveable 11 second car with trAction.
