ARE 4.8 Liter Heads Just Had the very 1st set of 4.8 Liter Stage II heads installed at ARE. A new design of Wade's. Went 10.76 @ 125.64 with a 1.433 at 3350 lbs 1st time out. See Drag racing section for more details.
For those of you that know the ARE dyno never puts up huge dyno #'s but they run at the track. These #'s however I was very happy with.
HP = 431.7 and Torque was a whopping 468.5 through the mufflers, an A-4 and a strange 12 bolt.
Sure seems funny to run these #'s from other shops you need to make 475 RWHP
Real #'s are proven at the track

Uhhhh... 4.8 heads are the same as 5.3 heads. And your torque numbers are squed by your convertor. I hope you don't think that is what it really made. None the less, they are nice numbers and times.

And as far as the skewed, I have had this convertor dynoed twice prior to this at much lower torque #'s.
Thanks though. I really appreciate all of the know it alls on the board.
BTW I only posted #'s for the "Dyno Queens". I personally don't give a ****. The times speak for themselves.

Beast96z, thanks for the props. Not trying to be a dick, just posting the #'s from the pulls which I was standing there for. As I said accurate or not these heads are running strong. No tricks were being performed.
The difference from a 5.3 is the chamber. I'll let Wade or Dave post up to tell you about them. If not, give them a call.
There is also more in it. I'd be happy to line up with Brent (Cartech's car) same weight same track
Yes #'s were locked.

Yes the heads are the same, even chamber sizes. We are very pleased with the results! 10.7 H/C car is flying at close to 3400lbs. We do however install new bigger seats and valves (2.055/1.57). Re-shape and open up the cumbustion chamber. Also new one-piece bronze guides are installed.

From: Your Reality Check Bounced...
that abnormaly high TQ number is the result of Torque Multiplication from the converter....My STOCK motor made 450rwtq on MTI's dyno....it's a 4000 Vig....but when u flash the converter on the dyno you "Trick" the dyno w/the torque multiplication....you have to get to 3rd gear and use a Tech 2 and lock the converter then nail it.....then u will get the TRUE Torque numbers..

Keep your #'s to yourself though because I really don't give a ****.
