Default Eps 226/230 or f13

Hey guys I've got an eps 226/230 on a 114 sitting on my floor right now with the necessary parts to go ahead with the install. My car is a DD and I wanted something street friendly but still have a lobe to it at idle, and this is what I ended up with.

Recently I've been eyeing up the f13 on a 114 lsa. I want the higher lsa to help smooth the idle. The f13 offers a little more duration and brings up overlap from 0 to 3 degrees.

My thing is that I dont want to regret not going with the f13 in the end. Will there be a power difference and will the extra few degrees of overlap be noticeable in the idle but still allow it to be a comfortable DD around town not shaking the car to death?

Go with the EPS cam. You're not that much different with the F13.

Keep the EPS cam. Geoff knows what he's doing

Thanks guys I know Geoff knows what he's doing. The 226/230 can is a proven performer. I just wonder if I'm leaving anything on the table. The cams look similar but by adding duration with the f13 you also gain 3 degrees of over lap which is a significant amount. So just wondering y'all's thoughts on that!?

I wasn't terribly impressed by the F13 but then again my trans failed on me so I never got to see what I could really run. It drove well, cam lope was somewhat tame. I only trapped 113.5 with it.

You will almost always be leaving power on the table when your main concern is drivability and idle quality. Also, In my opinion, I don't think a 114lsa is going to idle much better than a 112lsa cam with the same duration (maybe a little). It sounds like you want to go with a larger cam than your original choice. If your already thinking that you should have gone bigger, then I would go that route in the first place and avoid doing a cam swap twice.

King if you only trapped 113 with the f13 you had some problems.

I have run cams from both geoff and allan, they are both on top of the game.

I run the EPS 226 230 114 in my Camaro. I very happy with the performance and drivability. I don't think there will be enough of a difference to justify buying the F13 when you already have the other cam.

I agree that something was wrong. I only picked up 22mph on the back half and my trans died a few days later. So either my SS3600 was shot or it was my trans slipping.

Now rereading what I originally posted wasn't what I meant to come off as lol

Even before that when it was running well I thought it was an ok cam, definitely not an all out performance cam but a good daily/middle of the road cam.

Sorry for the confusion my original post made.

FWIW my F13 only made 361 hp with Hooker 1 3/4 LTs, OR Y with a 4in FM merge and DMH 4in cutout, SLP lid, LS6 Intake, Ported Tb, and FTRA. I felt my car should've made more power but oh well new setup is in the works.

Thanks for the reply man. I know I will always be leaving power on the table if I go for driveability. But I want as much power as possible while still retaining most of it.

No disrespect but on a 112 the f13 has 7 degrees overlap while on a 114 it cuts down to 3. 4 degrees of overlap will certainly make a difference in sound and power, correct me if I'm wrong.

I think you'll like the EPS cam you have. Install it and enjoy.

I still don't think you will see much of a drivability difference between the two. If anything you will notice with the cam on the 112 the power will come in a little sooner than the 114. I think most of it comes down to tuning for drivability with only a 3-4 degree difference.

thanks for all the replies guys. the eps is currently for sale but if i'm going to take a bath on it i'll just run it instead.

just to be clear though you all dont think hte added overlap of the f13 will make much more power? if its under 10 i wont even bother but i was thinking it was gonna be 15- more??

I can't see it being much. There's more to Geoff's cams than just the advertised specs, though... Like not beating the ever living **** out of your valve train.

I daily drove the high lift F14 for a few years with no problems. FMS cams are not hard on the valve train.

That being said I wouldn't bother getting rid of the eps cam for the sake of trying to pick up more rwhp. It will not be worth the lost money on saling the eps cam.

Im running a EPS 226-230 112+2 right now. Made good power for cam only. Has a nice lope to it and after I got it tuned I can jump in it and drive it anywhere. One day I plan to stick a set of ported heads with it for a bit more power. I like it.
