Rick,
My only caution, based on many years experience in the trade:
Unless you are planning to use the car for racing only, using racing fuel,
do not exceed 9 to 1 compression. Your engine is virtually guaranteed to
ping and run on, causing expensive damage to pistons and bearings, if you
exceed this figure. 92 Octane just cannot handle that high a compression
ratio.
