Does anybody remember when the list price for a new fast combat engine topped $100? The reason I ask is that there is a new speed event of interest to me, Southwest Sport Speed, which is for Fox Race planes, but with any engine up to .36 that is front intake, side exhaust, and originally cost less than $100. With inflation, this could make some of the older combat engines competitive, possibly along with older .29 f/f engines. Tanks are limited to suction, so venturi restriction would be needed in an engine designed to run on pressure, but I don't think that would be a problem.
Also, any ideas where to find historical information on engine prices?
Thanks,
