Ready-to-Ship vs. Custom
Del West is universally recognized as the leading manufacturer of titanium valves and lightweight valve train components
worldwide. Our custom titanium valves and related lightweight valve train products are currently used by every FIA
Formula 1, NASCAR Nextel Cup, Busch GN, and Craftsman Truck teams.
The same quality and performance that make our custom products superior are also available for rapid delivery from
inventory, for commonly used circle track, drag racing, and road racing applications. These Ready-to-Ship (RtS) components
are primarily intended for small-block and big-block American pushrod V8s, but are often very suitable for other engine
configurations, as can be see from the specifications provided in the following listings.
For custom applications and delivery schedules, for information on our hollow-stem valves and wide range of applicationspecific coatings, and for technical services and support, please contact our engineering or sales staff.

FSAE Performance Valve Train System
In support of the Society of Automotive Engineers’ Formula SAE competition, Del West has recently developed a complete
Performance Valve Train (PVT) system for the most popularly used engines, and offers these systems to qualified buyers at
special, discounted prices.
Currently available for the Honda, Yamaha, and Suzuki 600 cc engines, the Del West PVT package includes forged titanium
intake and exhaust valves with chrome nitride (CrN) coating, lightweight locks and retainers, manganese-bronze valve guides,
and beryllium-copper (BeCu) valve seat inserts.
To qualify for the special Formula SAE system pricing, orders must be placed via an accredited University purchase order,
and are limited to a maximum of two (2) engine sets per calendar year.
Contact the Del West engineering or sales staff for additional details. Included with each PVT system is a comprehensive
technical guide as wel as SolidWorks component CAD files.
