Hottest road usable cam. Not a good traffic cam. Lumpy idle. Not very suitable for small bore units unless fully prepared with big valve head. Very strong mid and top end power. Rev range 2,000 - 7,500 rpm. When used in Sprites, Midgets, and Morris Minors a slot drive oil pump is required.
 
 
Question:
I bought a Spridget race car. The documentation says this is a fairly wild cam built for 5000-9000 rpms. Cam has an end stamp that says 4D 73. I'm thinking it may be a good idea to take a step down to something a bit less radical until I can get to know the car and learn how to drive it. The car was built for SCCA racing, but I want to do track days, and eventually race it vintage. What do you recommend?
Answer:
While I am not familiar with the designation on your cam if you are right about the 5 to 9K rpm band I can agree with your concerns.  Bearing in mind that a camshaft is only one part of the system that generates power.  Typically a cam has to be complemented with the correct jetting, exhaust system, etc.  I would think a good starting point would be a camshaft such as the Kent Cam MD286. This cam will perform well from 2K to 7.5K.  If your motor was designed for a 9K cam it could be made to work very well.  Both ignition and fuel ration will probably need tweaking and the absolute best option is to find a local Dyno shop that will let you dial in the best of it all.
