They also had a pretty stiff spring in the plunger assemblies, so may fair pretty well at high rpms.

I believe Howards does supply Morels, and have spoke to several other builders using them (Morels) now with good results. I understand that Dave at SD supplies the 'new' Comp hyd rollers which are good, and have a 'D' in the part number (I have not confirmed this, word of mouth). Crane makes their' own from what I've heard, are good, but are considerably more expensive. I've heard by word of mouth that folks are having luck with the Scorpions, but considering the source, I didn't want to take a chance.

I was sweating the selection as I correct issues on the Olds engine, and struggled with going hyd roller over solids. As many know, I've had great success running solids on the street, driver has near 100k miles, and no issues. And I have not experienced adjustment intervals many speak about, or loss of needle bearings. I don't have a rev limiter on that engine, and I let it go until it doesn't build any more RPM.
