Here is the e-mail I recieved from Tim this afternoon. I think it says it all.
Hi Terry, Put a few runs on your baby today and get this. The only standard pattern low port dyno headers I have are 2" primaries with 31/2" collectors, (we use 2 3/8" on high port heads with 4 " collector) and we have to run 4 mufflers in the exhaust system to meet local noise bylaws. With your engine more than a little "corked up", it still made in excess of 906HP! I spent most of the day sorting out a mid-range over-rich condition, but torque was still in the 800 foot-pound range. The dyno was overmatched trying to adjust the load from 4000-7000. When the secondaries opened, we where hitting the rev limiter so fast it was tough to manage, and power was still climbing past our shut down speed. We kept running through parts of the power band so fast that the computor was having quite a time getting a reading. The only experiment I made was putting Stage V rockers on the exhaust side to replace the Norris. (you already have Stage V intakes) They seem good for about 20 HP, but I cannot tell if they were just compensating for the restrictive exhaust, although they do have better geometry. This thing idles smoothly, hits 900HP @ 6000 rpm, and should still make an easy 950HP uncorked. There where no water or oil leaks, unlike those pesky Holley carbs. The carbs are close enough that you will not hurt anything, and with a little tweaking, you should make more power at your elevation. I haven't down loaded the camera yet, but I will pass that along. I will go through a final inspection of the valve train etc, and then button her up for good. The low lift camshaft will give you pretty good street service, and I think the power will get the job done. One thing's for sure, if you need more speed at freshen up time, this package can be tuned to1000HP plus with ease. Tim @ FHO
Since no gear head thingy here, thought I would post this is a dual four hemi going into a street car.
