Hydraulic Roller Lifters w/LA Block?

well this is the cams problem , just as one guy told you the base circle of that cam is to large a dia to allow the lifter to set further down the bore at max lift the lube over all lift has tobe reduced , if you want the same lube profile . my cam grinder can and will regrind it for you , well as long as he has your cam lube profile . if not he can pull that off your cam and build the profiler to follow . redline racing cams 408-313-0145 spiro jennings (owner) . hope you get what you need done .
