SB Crane Retrofit Roller Lifter Issue

Just to put some closure on this issue I called Brian to ask about a smaller base circle cam and he says its as small as I can go. Next question was lifters; would another brand lifter make a difference. I called Crane and they told me the distance between the bottom of the wheel and the top oil groove is 1.427". I called Brian back and he is going to see if he can get a lifter with a lower top oil groove.

Most believe that what I currently have would likely work. But before ordering custom push rods and assembling the engine I think its best to see if a different lifter might improve the lifter bore to lifter oil groove relationship.
