QUESTION:
Basically would using a xer lobe with 1.8 rockers give me close to an lsk lobe for ramp rate(More, Less)? Would 1.8 ratio with an x-rpm give me close to the ramp rate of an xer(More, Less)?

IE:
A 224 .581 comp xer lobe (with a 1.8 rocker is .615) lift for the intake and a xtreme rpm 224 .568 lift on the exhust (1.8 ratio is .605) on a 111lsa (open to suggestion on a 110 or 112 +?)

PREDATOR-Z

That is not a good idea. The ramp rate of the XE-R will be too much to handle by the rockers and you'll experience difficulties, like floating.
If you want more lift just swap cam.

darn, Thanks, just trying to avoid swapping the 1.8's I already have for 1.7 but still take adventage of the great low end tq and under curve power of the lsk / xer lobe combo for road racing/hpde on small, hight flow & velocity runners (202cc)w/ stock cubes

Pred z, Thanks for your answers on other's posts as well, I really appreciate and get a lot out of them.

You could probably design a cam that takes advantage of your 1.8 rockers. People do it all the time.

What PREDATOR said. With the aggressive ramps on newer cams almost all of them say not to use rocker arm ratios higher than stock for a street driven car. It will destroy valve spring life.

On the bright side you could always have a custom cam ground to use with your current 1.8RRs

Or it shouldn't be too hard to find someone who will trade their stock rockers for your 1.8's.

Someone would want to trade their stock bearing spillers for my yella terra 1.8 shaft mount roller?

Thanks guys,

I'm going to look into a custom grind or just selling the 1.8 yt and buying the 1.7's and use the cam to limit the hp to the stock bottom end what say 475 rwhp & tq or something like that.
