That .642 lift intake lobe is an absolute waste on stock unported castings and is probably hurting you more than helping you. Contrary to the internet experts, it's worth almost nothing to go high into the .600's lift on a stock head, especially the 853's which die hard after .550.
The FM13 regular lift (.595/.588) cam is more than plenty for a stock cylinder head.
That being said, your #'s aren't that far off. I personally don't even like dyno'ing customers built A4 cars because more times than not you're going to get your feelings hurt. Stalled A4's are not dyno racers, race them @ the track and let the M6 guys play the dyno games.

Well I think my converter is done for or maybe it's my 3-4 clutch pack but I'm looking onto other brand converters. I think I'm going to move away from the Yank and I'll most likely go PTC or possibly an FTI unit.
Also going to get a new trans while I'm doing this which will eat up the heads fund but I'd rather put a freshened trans in and be ok. So I have some calls to make whenever I get free time. Makes sense why the car dyno'd low.
Thanks again everyone for your input.

Saying AI's heads can beat ANY cylinder head out there is a stretched statement.....If this were true his LS7 castings would be king of the hill, and there would be no reason for something like the Mozez, or the LSW heads to exist. Not to mention, Phil probably wouldn't be porting aftermarket castings either....
Indeed, and I appreciate the kind words. It was just a well thought out combo with good parts. When you sweat ALL the details (valve spring install height, lifter preload, actual camshaft ICL, valve events, good timing set, etc) on an LS3 you can make some damn good power with a relatively small camshaft.
