Looking for a hydraulic roller cam recommendation for my Stage 1, 274". I drive it on the street and take it to the track on occasion. GTQ 76 turbo, M&A heads, current cam is a 218/212 flat tappet (Comp Cams). 9.1 compression, Oliver rods, JE pistons, Buick Motorsport crank, 3:42 gears, 9" Art Carr converter (3400 stall), 2004R, PTE front mount. Going to a roller because of the problems with cam lobes/lifters due to the reduction of ZDDP in the oil but at the same time increase its performance. Appreciate any information/experience, thanks.
