To make those "hogged" out heads work you will need to up the RPM band that they operate in.
While this is not the best course of action for short block longevity, the extra RPM's "should" get your velocity up and allow you take some advantage of those heads.

Go with all the rear gear you can stand, turn the RPM's up around 6900 to 7200 and you should see more gains...

Agian this is just a band aid fix for the poor heads but should help...

Good luck.

And to think that ARE was going to be my choice for a head/cam package.

Look at Ragtop 99's post on page 1:

</font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif">ARE S2 2.08/1.60

Bolt-ons, 12 bolt w/3.73s, YTP 4200

Dyno:
locked: 378HP @ 6100, 362TQ @ 4800
Unlocked: 365HP @ ~6300, 485 TQ @ 3100.

ARE 346 motor & Yank YTP 4200

The ARE cars here don't seem to be faring too badly at the track. Still, I'd like to see more track times from more cars.

Guys have run mid to low 11s on numbers like these.

I'm asking seriously; not trying to imply anything.

You mention cammers with stock heads dyno'ing large, but (1) are dyno results the best way to make these comparisons? (2) do you think ARE heads perform worse than stock?

Default Re: Heads and Cam -- Post your info

Nick said a LONG time ago that he doesnt think that other shops use big enough cams. 95% of the time, the bigger the cam, the higher the numbers. Kinda like boosting flow numbers with those big valves. I'm just saying that MTI's track and dyno results have surpassed ARE's with smaller valves AND smaller cams. So, in conclusion, I believe that ARE's heads are inconsistent and very badly ported for them to be such a big expensive shop. To make up for this, Nick puts in larger cams (which IS the smart thing to do since Ive seen shitty results with other cams and his heads) to make up for his heads. Perhaps he shoud shop at SAM for his employees.

It's hard to say how MTI's and ARE's strokers compare...truth is...they don't compare. Pound for pound...period.

Alot of people will say..."you need this and that." Other shop's customers dont need EVERY single little mod or free mod to get 420rw on a H/C car or 490+ out of a stroker. If you guys are happy with what you've got...then more power to you. Do what YOU want to do...I just wouldnt do it with ARE heads.

Examples...I think just about (im saying 'just about' because i dont want to go back through this big thread to read all the results) every ARE-headed/single duration cam'd car has low dyno numbers and/or track results. He won't admit it, but jmX is another example, same with Visceral. <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> Anyway, another is a guy on another board a while back that used an LS6 cam and ARE stage one heads. He wasnt happy with his results. I think myself and Chris ARE 360 had some words about that one. Although, Chris has had good results from his ARE motor. With stage one heads (2.02/1.57 valve and probably more like stage 2 porting) and a B1 he made good power even at 9.7:1. with compression and an ARE cam, he made good power again. Its hit and miss with them and usually (sadly enough) miss. Id just stay away.

BTW, those high 11 117 results ARE very old but i dont think Eric went any faster. Chris E. and Mikey went faster...but it took some work. Again, hit and miss.

Default Re: Heads and Cam -- Post your info

H/C make/stage: CNC Inc. Stage II
Head Specs: 2.02/1.57/72cc
Cam Specs:Comp Cams 218/226 527/535 112, 4* advance ground-in
Dyno Numbers (and location): 402/378 @ Norris Motorsports, through the cut-out
Best track time (street/radials/nittos) & location: 12.33@115 with 16" Nittos, alternate driver, and pre-LS6 intake @ Orlando Speedworld 12/2000
Best track time (slicks) & location: Never used slicks
Major Mods (non std): Lid/MAFT/Grots/tuning/SPEC clutch/LS6 intake/stock cat-back/cutout
Comments: Combo is reliable if the valvesprings aren't breaking. Just switched from Rev's to 916's hoping for more than 20K miles from a set. Wanted 400rwhp before the intake, thus I still want more area under the curve. Contemplating cam change.

Heads: Andy's Auto Performance Stage II 5.3L heads. 2.02/1.57, 11.6:1 CR.
Cam: AAP Custom Cam 227/227 .591/.591 113 LSA
Dyno: 420 rwhp and 400 rwtq with no custom tuning

Other Mods: Grot 1 7/8 headers, LS6 intake, 4.10 gears, bolts ons.

Comments: These heads are the most bang for your buck IMO. Awesome power and awesome drivability even with no custom tuning, I'm hoping that once I get custom tuning I can add more fuel/timing and get around 430-440 out of the setup, looking to run mid 11's @ 120+ in almost full weight car
