Thunderchicken w/ Advanced Induction 21deg CNC'd TFS Heads & HR Dyno Results

I edited it just for you.

I haven't made any concrete plans on what I want to do. I want to get a 10 second slip out of what I have and think it's a possibility on the right day. Car needs a paint job as well. I've always intended to put the bottle on this motor. Maybe that's next... I dunno...

Thought you guys might like this. I was sorting through some of the results guys have emailed in and realized that I never posted this up.
It is a 397cid LT1
Ai CNC'd 21deg TFS Heads
Ai Hydraulic Roller Camshaft
Ai Street/Strip Ported GM LT1 Manifold
M6, 12-bolt, 4.11's
12:1 on 92/93 Octane
The car previously had another brand ported LT head, LT manifold, and HR cam & with the old setup put down 433rwhp. The new top-end put up gained from all the way down at 2500rpm when the pulls started (it was up 40-50lb/ft at ~2700).
V8Muscle has a run down on the car specs prior to the top-end swap here
Worth noting, the roughness of the graph is due to not applying dynojet's curve smoothing. Most of the graphs presented online are shown w/ max smoothing applied to make them more presentable.
Hope you guys like it!

I wonder where Alan has been hiding ? doesn't he check the forums anymore I'm hoping he did all this work to come back to the shootout we missed him last year.

As rarely as it happens, I agree with SSRRR that the LPE heads would have done better without a nitrous grind in there. 236/248 on a 110 is going to be lazy on 396 cubes with an LTx manifold. Yes the H/C package made impressive gains, but I'm sure that stock casting LPE head could have made 450+ with a properly packaged camshaft. To say a 236/248 XE grind is as close to optimal as your camshaft doesn't inspire much confidence
Did your heads do great? YES! But lets not disguise the previous combination as "thoroughly developed" and imply your heads will bolt on 40-45 rwhp with no changes. As for a question... what's the Min CSA on the 21* head?

I don't have to imply my cylinder head alone will put up huge gains over many others - it has been repeatedly proven over the years.
No.
I had considered a budget cnc work deal to port the version of the head that TFS sells, but don't care to put my $ into it. If 6 or 8 guys got together and sent in a $500-1k deposit I'd take the time to develop a program for them. It'd likely end up at $1k or so total for labor.
Some people call them nasty, some people call them stupid. When talking about street cars, it is hilarious what guys try to do.
Mike has a video for everything. Last I spoke w/ Alan he was quite busy.

Like I said, it doesn't really matter since you provided a bolt-on PACKAGE that eliminates the trial and error, and the proof is right there that it works as a whole...I just feel you are selling yourself short on the benefits of a modern, properly specced camshaft.

I know of 4 on this board that post pretty regularly right off the top of my head. There are plenty of LT1's running around who don't post on forums we never hear about as well with Tax season coming around I'm sure there might be people who are running them as cast who would love to get them ported but if there is no money to be made like the AI rep said no reason to develop the program.
This is more than likely the route I will go down the road and with awesome results like AI always puts out seems like the way to go

man have i been asleep or something to miss all this fun?
I've got a lot going on but will say that there was a dyno pull after that one that did make 504rwhp. The stuff works.
Thanks for all the compliments. Car does have quite a history.
The only detail i will leave you is this setup ran 11.17 with some real issues. That is what i'm working on now.

I wasn't trying to start a fight or anything, still not sure what you are getting at. I'd bet this thread has plenty of people thinking about it already.
