Current mods...
3200 stall, pacesetter lt headers, ORY, 243 heads.

Goal is daily driver with a little track time.

Thanks in advance for imput.

Talk to pat for tony mamo And go custom. Get a cam specifically tailored to your heads and to your liking. I wish I had from the beginning.

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.

TSP 228r is a great daily driveable cam that still give some good results at the track.

Something from futral or eps

I read a few guys went with the TR224 cam and got good results.....thought the TR228 might be too big

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.

I would look ino something custom from eps. I would maybe go 226/230 or 226/234 both will drive like stock and offer much more power than a 228r. The 224r and 228r make good power but they are older technology

PREDATOR-Z

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.

^ werd. on these 1940s-era push-rod single cam motors without VVT, that is.

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

PREDATOR-Z

Ah sooo, and you can of course quantify that statement^^ based on years of data gathering?

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.

Of course! Let me pull out my log book of every ls cam install from the past 15 years! Come on man, you're arguing just for the sake of arguing. If cam technology never advanced and couldn't make more power or the same power safer and easier then why do cam designers like Martin, Geoff, Patrick G etc all develop new designs and experiment with different things?

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.

Btw, I'd run an EPS 226/230 112+2. It'll make for a nice daily that has good street manners and a good powerband.

PREDATOR-Z

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

JakeFusion

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.

PREDATOR-Z

Well, yes; But if working on engines pleases you and you know you need the immediate power xer can provide, they are lethal when in a well thought out combos.

JakeFusion

I agree. You know my thoughts on XE-R and LSK lobes. And Comp in general. It's no secret. lol

Futral will get him right.
