Ai 228/236 .626" 114 Camshaft - Anyone run it? Just trying to gauge the use of Ai's more aggressive lobes. Anybody used it?
Whenever I see an Ai dyno, I'm impressed. But I'm impressed more when someone uses a Cammotion or Comp grind instead of an Ai. Seems like there's more power to be made vs a very easy lobe.
Phil told me they have an agressive lobe on par with the LSL lobe. I've asked him for more details, but haven't heard back yet. So, has anybody had any luck with that cam? Or any of the higher lift, more aggressive lobed cams from Ai?
It's between three cams for me:
Ai 226/234 .600" 113 using their easy lobes
Ai 228/236 .626" 114 using their LSL equivalent lobes
EPS 226/234 .600" 113 using the awesome lobes from Geoff
The EPS and Ai softer lobes can both run with PSI 1511 springs. And the more aggressive lobes, Phil recommended BTR Platinum springs (which I think I'll run no matter what).

This is not the cam you are looking for but i do have number for you and it drives like stock. See my sig for numbers, heads are ported by them also. In comparison, I had a Streetsweeper on my previous setup, this setup is more to my liking as far as driveability.

I was wondering myself how AI cams perform...I was looking at the SSHT to go with my AI 243s but didn't know if it'd be better to go w/ a EPS or AI grind with their heads.

I would go with the AI if you are going to have AI ported heads. My car put down some good power, 432 rwhp with a bbk and basically ebay headers. I bet with a fast and some better headers, it would put down close to 450 rwhp. Id at least look at a cam that will optimize the port job you are going to have.

Yea im really leaning towards that option...like a 230/238 .631 .631 or 234/238 " ".
Gonna email them and see what they think is the best option. Really wanting around 440-450 w/ an LS6 intake!
Sorry to jack thread! Let us know what Phil says...we are in the same boat lol!

He is traveling today, so it'll probably be tomorrow before he gets back to me. I am going to do the 226cc 243s though. I had thought I was going to send in my 241s for the HCR 219cc option, but I'd rather get heads that'll work on my next build and spend the money once.
And I plan to run Kooks 1-7/8" headers with their 3" true duals and a FAST 102. So really any cam will make a ton of power. I just don't want to give up drivability for 5hp up top.

I as well am goin with their 226cc option. If i could find a FAST cheap id def get one but chances of that are pretty slim lol.
Sounds like a solid setup for sure..and yes drivability is the most important thing. You wont enjoy it if its buckin and **** all the time lol

Here is the way I see it..
5-8 extra HP and possible valvetrain issues down the line, or give up 5-8 HP for very good reliability?
I ran an AI cam for 25k and never had one issue. I pulled it out and it and my lifters still looked brand new. I ran a more aggressive cam before that and it chewed the lifters up in 10k.
Go with the AI grind.

Another vote for AI. I went with the 226 CNC 799's and the 226/234 cam. Can't wait to get it in my car unfortunately my transmission decided to go out in my DD, so it will be after the Holidays before I get it in...

(226/234 .600/.600 113 LSA), I looked around also for numbers and idle clips. Found an idle clip but nobody has posted numbers. I'm hoping at least 440rwhp with my setup..

Yeah, the 228/236 is more aggressive than the 226/234. Phil said it's about 48 degrees from the .006" to .050" lift numbers which makes it about like the EPS or XE-R in terms of off the seat aggressiveness. But sits back down easy like the EPS/LXL lobes. Also has higher total lift like the LSL.

Man those are great numbers! Makes me really want a FAST to max the potential of the heads/cam! So are AI's cams just easier on the valvetrain because of the lobe design?
That's right about the size cam im lookin for...and soundclips of your setup dr. whigham???

I've been in contact with Phil at AI this week as well, but I'm pretty much leaving the cam selection up to him. I've got a forged piston with a .175 relief, ARP rod/main bolts, 243's, Fast 102, and 4.30 gears. I certainly expect to see a grind in the 23x range and with a tighter LSA, but I havnt thought much about lobe type until now. I wonder how much of a power or driveability difference the lobe aggressiveness actually makes.
