ET shows how well the car applies that power, track prep, and driving technique primarily related to 60 foot times.

Hell, the DCR on my own 383 is only in the high 7's yet that engine just popped 497 RWTQ and 543 RWHP with a larger header and some addtional time spent tuning on the chassis dyno. While more static CR would have helped both (the DCR and power output) my point is the engine still makes huge power in spite of a DCR most would agree is on the low side. I think to date it is still the strongest pump gas 383 I have seen but could be wrong.

I was just curious about the DCR in relation to how pump gas friendly this might be with a slightly lower SCR. You guys have got some great results. I am looking forward to my new combo coming this summer (does the madness ever stop?). I am going to be taking a tuning class so I can know a little something about tuning, but I will not be doing my own tuning...it is just a gee whiz like to know thing. John02Ss is my tuner.

Tony,
It was great meeting Saturday and I am astonished at the results I was able to put down for Dennis and you.
Oh, and I will get you the scanned image of the actual dyno sheet soon. Let Dennis know my neck is doing better today. 
I will try and make time to help you with your car as well very soon. 
As for the pther post, yes it is the same dyno, and if we can keep it seperate, it would be great.

This one needs to go on our featured vehicle link.
Hey Tony, I think you were the one I met at SEMA. I have not forgotten what we talked about, so email me.

Thanks again George for a job very well done.

In Dennis's case they were obviously damaged used heads so he spent some additional money on valves and a few guides that were broke....we then freshened the valve job, cleaned the heads, and milled them to 58 cc's. The only thing you would have to do ordering them new is to provide us with the correct mill info (58 cc's in this case obviously) and also opt for the 8019 spring upgrade (about $100).....Total cost would be $2565 direct from AFR including the mill and spring upgrade.
The key is getting the rest of the combination to match.....thats where all the money comes in. Make no mistake about the fact that Dennis's entire combination takes $$$ to duplicate, but the end results justify the price of admission.
BTW the cam was a custom ground hydraulic roller....not a solid
Hope this helps...

So Tony...
1. How many times did you remove the intake manifold during testing?
2. How many times did you remove the valve covers to adjust the rockers?
3. Why were there no CNC marks in any of the runners?
4. Why can I not produce these same results in my home-ported, GM-cast LS1 heads (which, by the way, are much more affordable)?
5. Can this setup run on 85 octane?
For the others out there, yes, I'm joking...Tony will certainly get it. Great results. Not bad for some "outdated" heads...

Tony,
One thing I have noticed as of late is that you seem to have an affinity towards the new, lighter weight Yella Terra rockers...do you consider those to be a good (albeit cheaper) alternative to a more expensive shaft mount setup (like Jessels)? Seems like they are doing their jobs, and quite well. I would also assume that they don't require any additional machining?
