I designed a cam for a Daytona Prototype car, over a decade ago.Stan Weiss wrote: ↑Thu Sep 12, 2019 3:01 pm I knew someone years ago that happened to. Luckily his was water cooled and he was able to run some hot water into it and was off and running agai
The rules limited the gross valve lift and duration at .050", so I designed a cam with a .007" lash ramp.
The owner hated it, because with the aluminum block and heads, they had to preheat the engine, to get enough lash to close the valves.
Lucky for me, they won the 24 hours of Daytona, so the owner got over the lash issue.
