Well i just finished re building my motor and need to know what kind of oil I should run for the first 500 mile break in time. Heres a quick list.

3 angle valve job
1mm over sized valves.
Stage 2 cams
Titanium retainers
skunk 2 valves

cp piston rings
ctr pistons
acl race bearing
acl main bearing
all ARP hareware.


Thanks in advance.


And i have searched but nothing quiet usefull

Royal Purple sells some break in oil and that's what it's actually called. I've used some inexpensive motor oil before which will work too.

My friend tested royal purple at UTI and supposedly it has terrible break down. Thats all he told me, Any other advice?

it's not that critical what you use really, having it tuned properly is more important. Roya purple is a good oil.
