About

From the high banks of Daytona to drag strips around the country and to cars on main street in your hometown, Chris Allmond has designed valvetrains for about every kind of internal combustion engine you can imagine. His work has won the Daytona 500 (and many other races), and is in millions of cars on the road today. His career has shown him a wide variety of applications with unique challenges and solutions.

A boater since before he could drive, and a certified engine nut, he as a youngster stood mouth agape the first time he saw a roostertail on a go-fast tearing across the water. It was only a matter of time before his love of performance engines and boats came together in offshore powerboating.

Over the years, he has noticed that the valvetrain of the big block Chevrolet is considered to be a weakness in the offshore boating community. Boaters simply accept valvetrain service every 250 hours as normal. This does not have to be the case. Follow this blog as he discusses what he would do to improve the durability of this legendary platform when it is applied to performance boats.
