Me a Yank 3500 Stall. Friend a Vig 3200 stall. Both cars basically the same suspension and full weight (Impala SS @4400lbs). Same 4.10 gears and I still run the 17" Impala rims on the front and 275/60/15 MT DR's on the back. He is running skinnies on the front and 28/11.5/15 ET streets on back. The best He has run is 12.66 with a Joe O in house tune and I ran 12.18 with a Bryan Herter mail order tune. I trap 112 in the 1/4 and he trapped 110, and I still haven't installed the LE2 cam yet. So what gives? LLOYD ROCKS

3,800 Lbs here 11.4's N/A and we are still tuning 
I love my LE-X Heads! I bet my wife will love them when I put them on her car 
We are figuring with a new converter and some more tweeking 11.2s or better N/A...then the direct port will make its appearance
NOTHING like hitting the A/C and power windows after a run and driving 100 miles home in rush hour traffic!
Then again we are the slow group

We've seen a surprising number of "315 cfm" heads flow 270 - 280 on that bench.

I can esily say I spent about $12,000 to $13,000.
Reason why di did this is cause I have a friend who put his LT4 setup, first time at the track broke the rear end, next he broke his drive shaft, the the radiator. I wanted everything new so it would be less likely to mess up as I drive along.

honestly I shouldnt have to set up anything...theres atleast 5 lt1 cars here on ls1tech with times to beat already.....I'm sure there has to be many people with aspirations of topping those times running through Bret's hands...
However, I'm open for suggestions....

Seen that alot since 2002 .... but I be willing to bet, it wont be a 23* head lt1 that I would be challenged with.... And if it is cool, cause the afr227's I ran are retired...

The biggest reason for that Shon is the heads were not enginered correctly for big C.I.. Most every thing out there is set up for 350-360 classes. Trust me it takes more then a flow bench to tell the story. A flow bench can not nearly flow enough to tell the story. it is just a measuring tool.
I am going to see how lite I can get the car with out giving up my A/C. The engine I have now makes good power but could probably do for a cam and converter change. The heads were designed around making power with a 380C.I. engine and do there job well.
I have a long ways to go but I am on the right track.
BTW you ever wonder Why 383s and 396s peak so early and stop making power long before they should? I used to

I agree with this so why do the 383+ when limited by the LT1 stuff and run into a dissappointment. Now if you have other means, ie different heads/Intake that can actually use the cubes and pump the air they go for it, no replacement but if you are limited, know those limitations and maximaze the combo to work properly.
A/C total is about 75-100#s(adding up the under hood and under dash stuff), if you are willing to do 'other' stuff for weight reduction then you can keep the AC.
I have not wondered why those cubes peak early and stop making power. I have a good idea why and most others do not recognize it.
