As some of you know I bought my 08z already modified (H/C/I) and the previous owner didnt know much about the parts used. I have a list of parts that were given to me but i found half the list to be inaccurate so far.

Since I have the heads pulled I figured I would try to identify the cam as well. When I pulled the lifters I noticed numbers punched into the cam visable from the #1 cylinder. The numbers are as follows -
Behind #1 intake lobe: EI25112 (or maybe the 2's are Z's)
Behind the #2 Exhaust lobe: C54-11II

I googled these but no luck. Anyone have a lead?

I believe "C54-11II" is a Comp Cam core...so you may have a Comp grind, or even a custom grind. Maybe reach out to Comp to see if they can give you some details. Perhaps the 112 in "EI25112" is lobe separation?

Those numbers will likely only identify the core not the specs. Those would be found on the end of the cam core which can't be seen unless it is removed.

thanks guys at least i know there's a good chance its a comp cam. I'm almost at the cam, need to get the steering rack out of the way next.

welp, got the cam out. found these numbers on the cam face. It is the same core that comp cams uses but I do not see a CC anywhere. sent an email to comp anyway. Does anyone have any leads on this cam based on these numbers? Google gave me nothing. Cam should have been installed sometime around 2013 to give yall a hint.

Well for those who are following along I'm 99% sure its a torquer 110. the 4727 matches the sku on katech's website and i measured lift at .616/.648 which basically matches Katech's specs (.615/.648). Now the question is do i keep it or not

Depends on your overall goals for the car. The torquer is a good low/mid-range cam but it dies off relatively early. If it's just a fun put around car, I'd keep it. You'll be able to enjoy the power without having to rev the motor to near redline.

yea but the car surges around town, and on the highway under 75. i got used to working the pedals to drive through it but if i have an opportunity now to switch cams for something more streetable then i think ill take it. I'm considering the B3 and the Alpha as it seems both make very good power and do not surge like the torquer.

Unreal

Thats probably more in the tune than that cam. Torque should not surge. If someone can't tune a torquer, they won't be able to tune an alpha or b3 either.

I would do the Alpha over the B3 if you do choose to switch cams. The Torquer 110 is ground on a 110 LSA, it's not going to be the easiest to drive but it shouldn't drive THAT bad.

You can custom grind a cam to nearly whatever you want, you pick the duration, LSA, and ICL. What you are confined to are the lobes (profile/design and lifts,) which will vary depending upon who's grinding your cam. Cam Motion has their own specific lobes, as does TSP, Comp, etc. (Comp has many different lobe profiles to choose from depending upon what your needs/goals are.)

I believe AHP has a custom grind cam comparable to the Torquer available on both 116 and 112 LSA's. Cam Motion's LS7 cams are ground on 118 and 117 LSA's, not too far away from the stock 120. Just as important as the lifts are the lobe profiles, which can make all the difference in the world when it comes to your valvetrain's lifespan. As long as you have the cam already out, I'd consider an 8620 core cam ground to your specific needs/wants out of your engine. If you're uncertain, ask a pro like PatG or Cam Motion to aid you in your cam specs.

this is all great information, thank you guys. I see your points with going custom grind, but after comparing a few cam specs it seems the Alpha will be a great cam for my application. I like the fact that I know what to expect as far as performance and it shouldn't beat up the valve train. Yes a custom grind would achieve my goals as well if spec'd properly. For my case they are 2 means to the same end. Also, Joe Cordes customer service has been phenomenal which is a big plus.

Agreed, I'm running the same cam and have no drivability problems at all. It's all in the tune my friend.

Unreal

Cant go wrong with alpha. Best cam ive driven in a ls7. If i went back to na that is what i would use.

Good to hear! I'll keep you guys updated with the results. Hopefully I'll be ready for tuning by November
