Well, as mentioned, many different combo's with many different oils but fairly similar weights. We find the Penn Grade 20-50 to be a very good oil, and based on the responses, probably about the right weights for us. I do like the straight 30wt idea, I was considering straight 50wt when I wrote this and it seems no one went that far, and in a Steve Morris SMX vid, I caught him saying they run straight 70wt in the SMX due to them running methanol and I thought maybe I should be running a straight one weight oil like 50wt. ......But none of you suggested anything that heavy.

But, in the Hemi, my issue, is probably more of a volume issue. Which brings me to my next question about cam bearings. I see Steve Morris running 55mm-65mm roller cam bearings on all his street engines and no oil feed holes, only splash oil....

So I do not have a raised cam block, but is that somthing I could do in the next tear down? Block off the oil feed holes for the cam bearings and go roller bearings? I never really thought you could run those on the street, but I am learning more and more about these high end engines, and what makes them live where traditional tech may not. I also know many Mopar builders won't build one of these without bushing the lifter bores....Another area I have not gone into...

What say you guys with after market blocks?
