My 243s are getting the 226 porting package done at AI and I wanted some input from you guys as to what would be a good cam to go with these heads as well as my current setup (stall, etc.). I'm not that knowledgeable about cams. Definitely looking for good drivability as well as power under the curve.

One recommendation was 234/240-113 .626

If under the curve power is what you're concerned about, I think that cam is too big. I'd look for something in the high 220's/low 230's intake and mid to high 230's exhaust. What is your desired RPM range, and how high do you want to spin it to?

Is there any advance in that cam?

LS1SLEEPA

Shift point now is 6200 so probably not looking to go over 6500. My current cam is 223/236 .612/.610 115

I don't think so. That's exactly what he e-mailed me.

Martin recommended this: 231/235 .617/.621 111+2 LS2 SNS Stage 2 camshaft

He said peak HP should occur around 6200-6400rpm with a 6700-6800rpm shift point.

I would trust what Martin says.

Thanks fellas. Going with SNS Stage 2 camshaft

Why not have AI spec the cam?

Really like the numbers on this suggestion...
Tooley's stage two as well as Martin's sns-2 will all make terrific power with street friendly manners.
With A.I. doing the heads, I'm convinced an old broom handle would run well.......metaphorically speaking

How dare you think of something that might be a great thing and not just go with whatever flavor of the month is being thrown around! Blasphemy!!

I've recommended this cam several times over the past few months. During cam motions sponsorship here, and subsequent website relaunch their cams have been redone and the LS stuff has really expanded. My shelf grind which was highly recommended by Spartan Performance is now defunct and this version seems to be the closest newer cam to mine, spec wise.

Because there's a reason everyone uses Ai heads and someone else's cam. Personally I would never give AI another dime.

OP, good move in trusting Martin with your cam specs.

I don't understand your statement at all. Why would you not give AI another dime? Are you referring to their heads, or to their cams? I'm a huge Martin fan, and run one of his cams in my car, but I'd have no issue at all allowing AI to speak a cam based on THEIR own CNC'd heads. I run AI heads, and they work fantastic.

I have seen countless posts by you complaining about your situation with AI. I am going with AI to do a set of 243s for my car. I have read countless threads and PM'd/spoken with a handful of people that used AI for their builds. You are the only person that continues to bash them.

I read through your build thread. I'm uncertain why you decide to post 416/388 in your sig for your numbers when in reality you made 426/405 which isn't bad given your exhaust setup could have used improvement and you were on a stock sized intake tract. Other people told you this yet you never responded and went on about how a cam change might help you get the results you want. People told you to keep the cam and work on supporting mods yet you ignored those too.

Here are two specific threads where AI heads with an AI spec cam made great numbers. Both builds used an identical 230/234 cam.

AI 243 makes 488/422

AI 241 makes 451/410

I am using these two because I have spoken with both users several times. One is a friend that's local. There are several other threads on this board, GTO and Vette boards as well, that show positive results from Phil's work. I don't post very often but your incessant bashing without heeding positive advice from fellow enthusiasts that will only help your build is showing your hard headed or just plain ignorant.

Lastly, as we all know a dyno is a measuring tool and nothing further. I could certainly be wrong here but I didn't see any track times to see if your trap speed was a better indicator of your car's actual power. /end rant

Sorry to derail the thread OP. As others have said, I am certain if you get with Martin or have Phil spec you a cam to your wants then you will be satisfied with either. Posting a 'what's the best part for this' thread will wind up being more confusing than helpful in most cases. Best of luck in your build!

I've got a 347" LS1 with AI 226cc 243's.

Ran a best so far of 11.26@122.8

I'm running an AI 236/242 .630/.630 111 cam.

I'm happy with everything but the cam after driving/tuning on it for 2 years. I feel given my 3rd Gen's weight (3400 race weight) and setup I should be seeing more mph. Plus it's a soggy dog below 4,000rpm, even with the 4.30's!

Based on that MPH and weight, what does that equate to in HP?
