has anyone ever ran the 107 or 110 cam from poston enterprises? if so was it worth it and what kind of idle and sound did it put out?
i ran the 107 smooth idle low 12s... but do to lack of zinc in oil now aday's YOU'd better think otherwise (roller) not flat tappet..:( or you'd be in it again.
i have the 107 i'm pretty sure in my car now...idles great little lop to it pull real hard..if you have the money i'd do a roller but flat tappets find to...i don't know about zinc in oil but i think you'll be safe:rolleyes: joel

I got the 107 in mine, pulls ok.

The only oil that I know of with zinc in it is the shell fire and ice. this was told to me by builder a couple of years back, he said to run that oil for break in then switch over.

Although I was like what? hmmm crap oil, I tried it on
the last 2 smallblocks i slapped together and ran it for break in with no problems.

But i thought zinc was banned...maybe its just flavor crystals added to it.

I'd like to find out more myself
