That's the cam I have in there.

My mechanic told me to break it in at 3,000 for 20 minutes. I then ran it at 2000 rpm for 10 minutes. ALl the lifters spun.

I guess I just need a reason why this happened for mental stability.

bummer...that is a good cam.

I had a purple shaft '.528 solid' get into porosity on one lobe, didnt waste it...but I knew it was a matter of time, so I bought another one and all was good after that..

typical porosity in the casting, thats hit and miss...and the only way to get the company to even acknowledge it...is to catch it in the early stage when the lobe is still good but shows lil air pockets the size of a rust spec/pen s roller tip.

so what was the seat pressure set to?
