Nice numbers bro. Im running a simular cam 224/230 .581/.588 114 and 5.3 liter heads that were milled to 59cc and custom ported. I have pretty much the same bolt ons you do and my car hit 407RWHP and 376RWTQ. on 4.10 gears. which is pretty simular, but Im impressed with the 395RWTQ. Is there something else you did? Whats gears are you running?
And trust me, I know when you talk about the power being alot. That combination we got is awesome cuz the power comes on early. I cant even stick on the street in 1st and 2nd gear. I think my compression came up to a 11.38:1. Me, on the other hand, am going to keep modding, except it will be another car! LOL
By the way, add some juice for the fun of it. 100 shot will do. I ended up with 509HP and 513ftlbs. Congrats again bro!

THX appreciate the comments! My bro in law is pushing the juice he sprays his mustang. I have stock 3.42 gears and all of the major bolt ons. Volant intake, nothing else that I can think of!

Well, once you come to your senses and do proper suspension and brakes, the car will feel not as fast again because the control will be so enhanced. Guess what you'll want then? 
Most folks equate lack of control with speed, consciously or not.
Congrats on the numbers and the curve, I am CERTAIN that thing is a beast on the street...especially if you have stock shocks!

Nice numbers! I just finished putting the same heads on my car tonight. With bolt ons and a custom cam ( 227/228 .649 .598 111lsa ) I did 370 hp and 366 tq. I am hitting the dyno on friday and am hoping for the same gains. I will have the before and after dyno sheets from just swapping the heads from the stock 98' heads to the PRC 5.3 2.5's milled to 59cc.
