It was a solid lift cam but i think my "advice" on springs was too much as i was running K-Motion 800 springs on a Crane cam 560/580 lift 258/268 with Howard lifters.Just to clear things here I'm not saying one or the other product was to blame! But i ran the VR1 oil as it is recommended for flat tappet push rod engines and now that i have a MP590 cam in there i will be running that oil again.I think the pressure of the springs was too much IMO.Right now i will be running a little less pressure then recommended.Still in shock mode I guess.I don't know who too believe anymore? Never enough spring pressure,too much spring pressure???
Just don't know why it hit #7 intake and everything else was perfect? Not even one full season.

I'm running a fast ramp Comp solid, 350# open w/double springs. About 1,000 street miles and a little dyno time. So far, so good...

I ripped the oil sample from another member here...
