I wondered what had happened to Thunderchicken, I haven't heard much from him lately. Glad to know he's busy with his car.

I honestly forgot you were SR, just remembered it was a mild cam. It was almost 2am when I posted that.

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...

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!

Phil that's bad ***. You always keep raising the bar with your products. Glad to see the Thunder chicken back out and running. Last time I saw it was when I beat it at the 2010 LTX shootout on a hole shot. I love that car.

Nice numbers! I plan on building a similar setup, 396 with AI 21* Heads, cam, and ported intake combo, but with 14-14.5 CR and E85. This gives me a great idea what to look forward to!

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?
You imply a car that has had more vetted & skilled hands on it than the overwhelming majority of LT cars simply hasn't in your estimation, and continue to assert your naivety by attempting to discuss cams by making assumptions based on #'s anyone with experience knows are the least meaningful.

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.

Nice job as usual Phil. I am going to be needing some stuff for a motor that I am building for a friend in a few weeks or so. I'll get a hold of you when he is ready
I'm around, text or email. I hadn't seen the new car - that's killer!

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.

Thanks, but that question has been answered in my previous post.

All of our aftermarket heads are based on bare castings to reduce the existing machine work I have to work around.

Honest question, you really think only ~10-15hp was from the cam swap? XE lobes are very mild, surely the cam you specced is using quite a bit more aggressive lobes? (I'm not asking about them, I understand from a business stand point you can't talk about the lobes you use and spec...which would be way more insightful information then just knowing the duration @50). It also has a more favorable NA split, quite a bit more lift, and a healthy amount of duration. I can't imagine your larger, modern custom cam NOT making a sizable difference both under the curve and @ peak over the old lazy XE lobed 236/248 grind that clearly wasn't specced for big NA power on a stroker.

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.

Very nice, nearly 500 RWHP on a HR cam with 12:1 compression. Thanks for posting.

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

Are the stock piston valve reliefs enough to clear the valves with these heads? Probably wouldn't gain much with this swap anyway. Maybe 5hp.

Yes they are. But you still need X amount of people to buy these heads. Because out of the X amount that have them, only a Y amount are then maybe want to get them ported.

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.
