EPS Lobes
EPS Lobes Is there any reason NOT to go with EPS lobes and stick with the tried and true XER?
I want to be as easy on my valve train as possible, while still making some good power and great sound.
Looking at 233/239/112 and 232/234/112(torquer V2).
Opinions, thoughts?
Currently have a TR224 with 918 springs. Stock block 98 LS1 with ported 806's.

None that I can think of. Nothing wrong with XER lobes they've been around a long time and certainly do make power. But like anything technology improves over time and there is little to no downside over the old stuff as is the case here. EPS lobes will make about the same power, be much easier on the valvetrain, and have better stability. No down side lol I would look at the eps 230/238 judging by those other cams
I had an EPS cam, loved every sec of it. It was a cam/intake only car, ran strong as hell, dyno'd 440hp to the wheels, and valve train noise was very minimal. I was running 7.425 pushrods as per Geoff from EPS.
EPS lobes were based on the LSL lobes with lower lift and slightly more seat-to-seat duration (the same as XE-R IIRC). So they actually make more power than XE-R because they are more stable and are just as fast.

EPS lobes are nice lobes... But I do question why more gen III folks aren't looking into later tech comp lobes like the QXI/QXX lobes or HUC lobes. Both are extremely stable, as they are designed for constant high RPM (circle track type racing). They lift high, but are soft on and off the seat creating a quiet under the hood valvetrain. They'll out power LSL's, XER's, EPS's, and still be quiet and reliable.

Verdad Gallardo I didn't know much about EPS but I figure if I am going to put in a new cam, might as well put in a cam that will be as reliable as possible for the rest of the valve train. Getting rid of my sewing machine noise would just be a added bonus.

Absolutely. There is nothing wrong with the TR224 but its not exactly what I want. I figure a cam swap and some cleaning over a weekend would be a nice project. Then I want to get a real tune.

I went from a copy of the TR230 (one step up from your TR224) which was designed by Geoff who runs EPS. Now I have an EPS 230/238 EPS lobe on intake and LSL on exhaust.
I added 243 heads at the same time so hard to know how much of the improvement was cam and how much was the heads, but the improvement was vast to say the least, especially off idle.
I would def look at the 230/238 for your car. Another benefit is Kip is grinding their cams now so you don't have to worry about lobe failure like Comp Cams.

Nate, deff look into them. I am running a very similar EPS cam and am quite happy.
If you are ever over by me holler and you can take it for a spin and play with the car.
LQ9, EPS 230/236 or 238 cant remember which, 799s, big converter.

If you go with EPS lobes you will get. 1 lobes that will be quite no sewing machine noise. 2 they make to most power than any other lobes. 3 The cam will be made of the best steel 8620 Aircraft Quality. 4 you will get what you order because all cams are checked on a Cam Doctor. You will get the printout of your cam not a computer generated cam card.

I have the same thing and it is noisy. Like you said it runs well though. Im building something new and will probably get another from him in the future. Gotta wait till the shortblock is ready and I have decided on heads first though.
