When visiting PRI, one booth we were sure not to miss was Scorpion Racing Products. Complete with robots and plenty of anodized parts, the booth was full of Scorpion’s products that cover the entire valvetrain system for your engine. We saw their full line of lifters and valve springs for many popular engines, but what really caught our eye was their Endurance Rocker Arms and Extreme Duty Racing Valves.







The Endurance Series Rocker Arms were designed for engines that are under long periods of stress or use. Available in many different ratios, these are available for just about any Ford or Chevy V8 both big and small blocks. They feature a lightweight design with short polylocks. Best of all, they are designed to fit under stock height valve covers, so there is no need to replace the ones already on your engine.







• Available in many ratios

• For high endurance racing engines including offshore powerboat racing engines

• Designed to fit under stock height valve covers with no interference

• Lightweight design with short polylocks



Also on display was Scorpion’s Extreme Duty Racing Valves. They make these valves in both Intake and Exhaust versions for BBC, SBC, LSX and 2V/4V Modular Engines. There are so many features for these valves, but check out the highlights.







INTAKE VALVES:

• Non-magnetic Stainless Steel 21-4N intake material

• One-piece forging

• Hardened tip

• Hard chromium with stem superfinishing for much lower surface roughness

• Double swirl polish with finer finishing

• Back-cut for important flow improvement

• Lightweight design with undercut stems to reduce weight and improve flow figures

• Very tight tolerances to allow smaller guide clearances reducing oil consumption through the guides



EXHAUST VALVES:

• Non-magnetic Stainless Steel 23-8N exhaust material - a superior alloy for higher temperatures and closer to Inconel than any other valve steel

• Hard chromium with stem superfinishing for much lower surface roughness

• Heat-treated hard tip with 54 HRC minimum

• Double swirl polish with finer finishing

• Back-cut for important flow improvement

• Lightweight design with undercut stems to reduce weight and improve flow figures

• Tapered exhaust undercuts to increase strength at high temperatures

• Very tight tolerances to allow smaller guide clearances reducing oil consumption through the guides
