I have a roller going into my side-oiler and should be able to give you an accurate power gain vs. the solid flat tappets which were in there. The only problem is that extensive work has been done to other parts of my motor to make the most of the assembly.

Like Duck said the other parts are need to be matched to the roller's optimal flow rates. Hey Duck - I was just thinking of you the other day - it's been awhile since you've posted. Give me a call sometime when you have a chance - I'm PM'ing you my phone number now. Take care!
