Yeah I am starting to see your meaningfull info and it makes me agree. I don't think he should break in on a roller its really overkill you are changing my mind, maybe driving is the best for a roller cammed engine. I drove mine and romped it some but not alot after a break in and stripped back off many parts. But that engine was studded also. (easy to take heads on and off alot as well). But many of those things because I really am a beginner doing all sorts of overkill in the beginning..but learning to back off some of those things. The so called wear pattern on my roller really wasn't a wear pattern at all, just my mind going ocd and perfectionistic on it. Sometimes I just take stuff apart and together again and measure all kinds of things with calipers and such. Its just a compulsion. I never made machinist,just an apprentice for five years and didn't go to college, numbers drove me insane if I wasn't interested on what I was working on. So I built a few laser engravers and made miniature jet engines...so what. One thing I am learning there is a gray area and in that area is not to break in roller cams anymore because its wasting time. But I will always use cam lube etc. on all parts and change oil filter and fluids. I would use that as the 'break-in period'. The lube filter and fluids. I don't wan't anyone to waste their time. My observations are merely that and like I said you couldn't really call it a 'wear pattern'. I was thinking about the hbeam rods and I suppose if you were building 650hp nitrous or something and aftermarket block then maybe, but I prefer forged I beam stuff for the 460hp range. Well I'm out hope I made some entertaining reading for someone. I am sorry what I said was a little misleading and bold to begin with, but I just wanted to share my experience. My first roller got ate because I used 1.5 rockers with 1.6 stagger, but it was on .550" lift. The lifters dropped and spun. And ask about a cam with a compatable distributor gear so you don't have to use bronze gears. I am diagnosed with OCD. It can be an ally & very crippling and disabling at times sorry.

 

so basicly what everyone is saying is that they don't really know so i should call lunati and see what they have to say.

 

I guess not then. Maybe we should all just go and stand in the corner!
Tell you what, call Lunati for your own peace of mind. Crane already says no break-in, let's see if we can have a majority rule here and put it to rest.

 

ok gentlemen, i know im using the afr 195 heads but what chunk of aluminum is gonna feed this monster i have been looking at the edelbrock performer RPM, and torker II
the holley stealth series
or a maybe a dart havnt really looked into them yet

 

RPM Air Gap. I ran my 383 with a regular RPM too and it was snappy as well.
