[DeTomaso] 408 Stroker Life Expectancy

[Ken Green]

As radical an idea as it may seem, maybe it's time to start building an engine build database (Chuck?).  None of us can build 20 motors and see what works best, but over time, a database with a description of the build, and how it performed or how it failed would be really useful.

3rd-to-4th shift focusses one's attention wonderfully well on driving but 
over-tightens the sphincter-muscle on most of us!"
