Well, not sure where you got that Motive gears whine, but my Motive 4.10 is dead silent. It just has to be installed properly. Richmond is the gear set that is commonly accepted to be the worst made.

If you're changing to a thinner head gasket, you might as well mill the heads as well. No reason to leave it at a low DCR when you could bump it up to 8.5+. It's not hurting me at all to be at 8.6-8.8. Long story, but basically I asked the shop to mill .030" off the heads, but when I got them to the garage my tuner measured the deck thickness and said he thought they had .040" milled, but we were in the middle of stuff and I don't remember the measurements now.

I still say that's a great cam choice, but I'd have done it on LSK lobes instead of XE-R. But to each his own. It should still be awesome for your goals. And I only say that because it's between my disappointing 224 baby cam and my very enjoyable G5X3. Sounds like an excellent compromise.

Just outta curisoty.. why would you put it in LSK and not the XE-R?? All the numbers are EXACTLY the same.. Nothing changes.. I will just have a more aggressive lift that is all. As far as HP goes what is the difference < 10???

With the same durations on an LSK lobe, the lift will be higher and the lift will come on faster. The result is more air entering the chamber and more air leaving the chamber for the given duration.

ahh i see.. but it wont be to noticable as far as power, will it? makes sense that they are at a faser ramp rate.. more air in/out

Maybe not that drastic of a difference, but I would guess there would be some overall gain throughout the entire rpm range. I cant really say though since I never ran an LSK cam. Pat G could probably tell ya, he uses LSK's.

My understanding is that it would give more power throughout the rev range. That way you'll make up a little for the small cam. I think that cam is a wonderful grind in either LSK or XE-R, but I still consider it small. I see the LSK lobes making up for the sacrifice. Not to mention, you'd have something really cool that others don't have.

And 10hp is 10hp. Sure, a good driver vs. an okay driver is worth over 50hp (I'm usually the less talented driver), but it would suck to make 441hp instead of 451. Not that those high numbers are to be expected. But you see the point.

Look at the difference between XE lobes and XE-R lobes. Nobody runs XE lobes anymore, and there's a reason for that.

yea i see what you are saying.. hmm that is worth thiking about. Remeber i am staying ON STOCK NON P&P HEADS!!!

if i do the 228/232 on a 110+2 the DCR is 8.15 and with .040" gaskets it gets it to 8.38.. That is now bad....


if i do the 228/232 on a 110+4 the DCR is 8.28 and with .040" gaskets it gets it to 8.51.. Now that is way better.

But going from a +2 grind to a +4 i will loose some TQ. But will the higher DCR make up for it

EDIT: I am jsut playing with some numbers

Wasn't on purpose...website appeared to have gone astray, and I kept trying to push a post through. I gave up and then now I see it went through twice. I have now deleted one.

Why do you think you will loss torque going from +2 to +4?

Yeah, not sure why you'd lose torque. But I've never messed with specs for a small-ish cam before. I'm very interested in this though.

I guess my thoughts are that if you're removing heads to use a thinner gasket, why not put some love to the heads while they're off?

You will gain tourqe by going from a +2 to +4 advance due to the increase of DCR by closing the intake valve earlier. You will gain down low at the expense of power up top.

All are @ .050

XE-R 110+2

IVO - 6
IVC - 42
EVO - 48
EVC - 4
ECL - 112
Overlap - 10
DCR - 8.15

XE-R 110+4

IVO - 8
IVC - 40
EVO - 50
EVC - 2
ECL - 114
Overlap - 10
DCR - 8.28

LSK 110+2

IVO - 6
IVC - 42
EVO - 48
EVC - 4
ECL - 112
Overlap - 10
DCR - 8.15

LSK 110+4

IVO - 8
IVC - 40
EVO - 50
EVC - 2
ECL - 114
Overlap - 10
DCR - 8.28

So what gives a better all around performance?

They are all biased to the intake side so they are all more suited for low end power. If you want some more upper end power, lose the advance on the cam to bring overlap closer to TDC. if you are looking for the most power with the highest DCR and dont mind giving up some high end power, go with the +4 LSK lobes.

really though all these cams will do well for what it seems like you are looking for: low end street drivability with the ability to compete in the ocassional street race.
