Arch not to go OT but why is 50 Wt oil considered racing oil, we sell it like crazy here and the performance guys love it.

I've been toying with changing Mayhem to synthetic... the Dodge is already on synthetic... maybe next oil change, which is coming up real soon.

Mobil 1 SYN. For both camaros

not really sure I asked a pro (I lived next door to a pro stock driver in Sugar Hill GA) and he said it was to do with the clearances (they also run very very low levels)

jesus i had no idea any 4th gen had a hydro flat tappet cam. Was 87 the change over year for v8s into hydro rollers? Think it was. Anywayz i thought the v6 3rd gen maros (late 80s time period) also had hydro roller cams. Im guessing im mistaken on that part now since i have no idea why they would change em back to flat tappets.

v6 went in only certain engines

well all 3rd gen V6s had the same engine as me, cept smaller bore, so then i guess that means all 3rd gen V6s had hydraulic flat tappet.

the 2.8 may have been roller I can't remember the 3.1 was flat though
