Default Ultradyne solid roller

I bought this Ultradyne cam off a member years back and do not have the cam card. The engraving on the end is G3984 309/310 R6.

Skip found this information for me off of Ultradyne catalog.
NR100 309 280 0.4507
NR103 310 280 0.4271

$180 plus shipping which was $33 last time I sent one to the NE United States.

Tim G at Bullet is doing another regrind for me. If he has some time I will see if I can find some more info about your cam. Exactly what it is. Is it safe for a stock block and all that.
I cam I have that I was told was safe for a stock block is not one click past the safe zone. Its 2 clicks so I am regrinding a awesome Comp cam with some proven safe Ultadyne lobes .

I bought this cam from Eric Vogel, GTO board name. He said it was great for a stock block as he ran it without a lifter bore brace. Skip found this information on the cam.

UD lobes? only group I found with a 309 duration
