Default Largest Hydraulic XE-R grind

So who is running the largest XE-R hydraulic roller cam or one with similar ramps? What does your valvetrain setup look like and what are your results?

Here is the XE-R chart. 248/.615 is the biggest listed on that chart.



Thats a pretty big lobe...

Good info once again, but from my understanding, thats not a complete chart there j-rod. i've got a 238 ex (non XER) lobe on my cam, and it's not shown. hrmm.. mark @ comp was telling me for some odd reason that the biggest lobe they had was a 242 at the time. perhaps this is a later chart, or i was just mis-informed.

I have a buddy @ Comp sending me the master Lobe Catalog. I will try to scan the appropriate sections and post them up.

i have a 236/238 601/605 on a 111 with 2* advance. stock lifters and combinations new ex-616 springs(stock bottom end). still working out tranny and converter issues, but the valvetrain is holding up fine and is not too loud either. we will be checking spring pressures after we switch from the 5.7 heads to the 5.3 heads. after we put the 400 tranny in, we can work on some more solid numbers

I thought the larger the LSA, the wider and lower the powerband was? I was under the impression that a smaller LSA narrowed and raised the peak?
