now to reply to the thread...."IMO" out of the box AFR comp.pckg. puts all these heads to shame.... when comparing intake cc's..... AFR's just have a really good ability to flow good #'s at real low lifts.....that means you can make a great powerband with the right cam....and that also means more usable power...and better et's....
ALL OF THIS IS MY OPINION...
I'm not trying to dog the rest of these guys....but I also trapped at 114 in my 383 with a set of stock pocket ported heads(ported by me) with a 4000+lbs. race weight too and with 2.19 60ft... da: was what ever CALIFORNIA SPEEDWAY is at......I'm sure that mph would have been better if I had ran my slicks.....

Beaner,
None of the 350 stuff is peaky either.... don't know where you got that from? At least none of the cams I do.
They are doing 380+rwtq now on 350's and it's a nice flat TQ curve. Over 350rwtq from 3000rpm to 6200rpm easy.
I really do mean it on the 2 weeks notice... you keep flappin your gums but gettin no work done. It's only 25rwhp SAE, can't be that hard for you.
travie319,
Funny thing is that i've found the low lift numbers don't mean much, you can lose flow there and the car makes more power and goes faster. Don't get to carried up in low lift flow numbers.

As far as weight some do go 4400+ but other can be much lighter, wheels make a huge difference on these as the stock Impala rims are something like 29lbs and wrapped in heavy z-rated rubber for a total weight of around 60lbs apiece. 15" steelies on front and you can be down to 40 apiece there and then 15" with slicks on back and again easily 40lbs or even lighter. This is signifigant because it is not just weight but rotating weight so reductions there pay off MUCH moreso than say taking out 80lbs(4 wheels/tires 20lbs apiece) worth of seats.

Look at the details on those other top Built/NA cars and those are best times with lots of effort into dialing everything in and in most cases extensive lightening.

Dwayne, I'm just starting to realize how big of a deal Ken's car is.... He was just another customer for us so I don't have a reason not to believe him since everything we did with him went well.
I didn't know he's the fastest NA Hyd Roller B-Body with a stock tranny to boot! Faster than 3 speed and SR guys.

If you want to look at it that way we could look at the 11.8 home built 383 home ported iron heads Comp 501(see tiny) 4L60E car I am leaving out some details there, but it is an NA Impala so those details couldn't mean much right 
.
That cam is 212/218 .488.495 and he has the stock stamped rockers
.
See my point on why a bunch of us on the b-body side of things want more info? Look in the feedback section of the b-body board too and see who you dealt with and just look at his previous posts in general and you will understand the skepticism.
Again I sincerely hope you guys have worked out some great details and this car holds up to scrutiny, but at this point the guys that know the b-body and the ones who have a lot of time and money into making them fast are not going to trust these results from that guy.
On the b-body board Lloyd brought up Franks 12.2 full weight 355 car, Frank has been around a lot longer without transaction issues and shares details hence the trust.

I believe they flow in excess of 500cfms and can let you easily obtain 700rwhp naturally aspirated.

I resemble that remark.Mine flow 380cfm and thats on the weak side of the sb2.2 field. We are currently at 740 at the crank N/A.

My buddy with le2 heads and Bret's cam went 11.7 at 121mph on a stock 10 bolt with 206k miles and with a pcmforless base tune. Come spring I'm betting the car does deep 11's at 124+mph.
