roller cam
 
I have a 350 in my s-10 with Vortec heads and a comp cams magnum 270. It runs okay but i am wanting more. i have decided to get my heads machined on to accept bigger valve springs. I am looking at installing a roller cam and lifters. My question is has anyone have this setup with vortec heads and a roller cam. if so what set up do you run and how well does it run. I am wanting the best i can get since the roller parts aint cheap. thanks for all the help

I don't have vortec heads but have a Comp Cams retro fit hydrualic roller cam with 520, 540 on the lift. The lifters are speedpro vertical bar style. They require the use of a shorter pushrod then stock that measures 7.3 in. While the hydraulic roller lifters are heavy as hell my motor still loves to rev. I shift at 7000rpm. There is no maintence like running valve lash like there would be on a solid roller cam, but im sure a solid roller would make slightly more power. It did cost me alot to have this set up, $200 cam, $250 lifters, $180 custom length pushrods, but it is worth it just to tell people it is a hydraulic roller. If your car is primarily used for street duty get a hydraulic roller but if it is only for the strip get a solid roller.
