RE: Spit 1500 compression

[uunet!morpho!alan@EDDIE.MIT.EDU (Alan Dahl)]

Tim Drabik has been asking questions about Spitfire 1500
compresion, pistons and heads.  I seem to recall somebody
mentioning that in 1976 *only* (?) there was a high-compression
engine option available in the Spitfire.  Is this true?  If so,
can I tell from the engine # if the engine in my '78 Midget
(which I removed from a wrecked '76 Spitfire) is one of
these?  It sure doesn't like running on anything but unleaded
premium, despite the manual saying regular is OK.
