A COUPLE ???'S

Every where seems to say you can run a .512" lift with the TFS heads, but that all depends on duration and rocker ratio. The only true way is to check clearances. As for solid cams, why? A hydraulic roller lifter in a 5.0 can make plenty of power, some guys run in the 12's with the stock cam, supercharged even more. Gear drives emit vibrations throughout the valvetrain, and I'm guessing it might put strain on the roller set-up, also the roller cammed engines have knock sensors and the gear drive would probably set them off and the CPU will retard your timing, not a good thing if you want to make power. Flycutting pistons costs around $150 at my local shop. A windage tray can cost from $110- $160 maybe more. Call Summit racing. If your considering these parts, get the windage tray, stick with a hydraulic cam, and forget the gear drive and spend that $250 elsewhere.
