I run a comp 54-428-11 in my dd and love it. Its a 228/230 .571/.573 on a 112. It has great street manners with a choppy idle (that sounds mean) with good low end torque. Thanks to Ed Wright (Fastchip) for the tune. Look at my sig for mods.

OP, contact Martin Smallwood at Tick. He will set you up with better lobes than the sharp XER. XER are good if you do not mind springs maintenance.
Martin will give you a grind than matches your setup closely.

That is a bold statement and the tech is still the same.There is no magic lobes. There is a tug of war with every design. You want something? Gotta give something back. Such is cam science.

There are no magic lobes but to say that technology hasnt come a long way is also inaccurate. Eps lobes and other modern lobe designs can make more or the same power while using using less aggressive ramp rates and going easier on the valve springs. sounds like a good advancement to me

EPS lobes are just as aggressive off the seat as XE-R, but aren't square shaped. From what I recall PatG saying they provide similar duration at .006 .050 and .200 to XE-R, but are designed to have a shape similar to an LSL lobe. They are an endurance profile, but probably the most aggressive endurance profile offered.

There was a baby eps cam on here (222/226) that made 430whp through a locked a4. The 228r and the like are still great cams but are ground on XER lobes which are proven but are very hard on valvetrain parts due to their fast ramp rates.
Newer lobe designs like LSL, EPS, and XFI will all make similar or more power in some cases but will do it with a slower ramp rate making it easier on parts.
Do I have a case by case basis where one made more power than the other? NO who has time to go look that up case by case? Is there plenty of evidence? YES. Searching through the dyno section will yield many results of small eps cams nearing or surpassing the 400whp mark cam only, something a 228r could only dream about.
I'm not trying to muck the op's thread so I'm politely bowing out after this. To the op. Again the 228r isnt a bad cam and will make good power and tq as it has been proven over the past 10 years. However you can get more power and the same driveability out of a custom spec'd cam from eps or Martin.

Man, I agree there is change, but not really tech.
228R not making 400rwhp, cam has the potential. I broke 400rwhp on a 224 xer lobed cam with -10* overlap. That was back in 01

XE-R lobes have always made power. To me, they are still the gold standard for power production. However, since EPS lobes are essentially the same with better valvetrain dynamics, I would recommend them.
Plus, with EPS cams, you get them ground on Billet Cam Motion cores and you get a cam doctor report with the cam. Those two things make an EPS cam worth more than a custom Comp cam.
