Personally I would have a solid roller in my car if I thought the added expense of the pressure feed and or bushed roller wheel made that much more horsepower per dollar. I have a limited budget for my car and I have other places to spend $1100 dollars instead of a set of lifters that MIGHT gain me a few horsepower. The bushed roller is a safer option on the street because it will at least warn you when it fails and wont send needles through your engine. Trust me Lee I thought long and hard about dropping my credit card down on a roller valvetrain VS a new solid cam and liters. The entire roller deal would cost me just under $2000 with some careful shopping and that is just not in my budget for the benefits it provides. I really don't look forward to pulling my rockers back off and re-installing my inner spring then putting everything back together and re-lashing my valves then draining the expensive break-in oil out after a few days of running.
