I would certainly require premium gas if it doesn't have a knock-sensor.  I
have heard of some aftermarket products.  Clark's Corvair Parts was selling
them after they dropped their water injection kits.

This engine seems that it should be just the ticket.  One thing gives me
pause; the compression ratio is 10.1:1.  That must be the real source of
