Question about p&p heads and cams

ok.. to start things off I just got back and I hit the refresh button and I see some crazy **** going on??? I guess they updated the looks or somthing.. But anywhy back to the topic. I want to make my car faster with out adding a superchager or nitrous. I have 2000 to spend and I was thinking that heads and cams would be the best thing to do for more power. My car is an automatic. But if im only going to get 20 or so hp for 1500.00 dollars then ill find somting else to spend my money on! I want to see mid to low 13's in my car. I just put the headers on and im going to the track saturday in hopes that I break into the 13's.

Remember...the springs in PI heads can barely take the stock cams. If you want bigger cams, even mild ones, I recommend new springs. You'll spend every bit of money on those heads. I work at a shop, and to do my heads up (p&p, cams, springs, and all the stuff...gaskets, bolts, etc.) it would cost right at $1800-2000. And that is my price( I don't get much of a break)...customer would easily be $2500 up. Labor to do heads is 14 hrs...at whatever the shop rate is...65-80/hr...you do the math. Add 100 bucks for new bolts (old not reusable), 100 bucks for head gaskets, whatever for porting, etc.. The list goes on. Doing the heads on a 4.6 is not really a driveway job like on a 5.0. Either save some more and get a charger, or get some nitrous. The NOSzle kit would be the way to go. N/A tuning works better on 4V's in my opinion.

Or, disconnect the front sway bar..that was worth .2 on mine, .5 on my cousins 347. Gears like 4.10 or 4.30 and some lower control arms will help. That should put you in the 13's.
