As cool as it is to rev the little 2.2S engine, the 2.4 with increased compression and a more modern cam (Mod S or similar) is generally quicker and much easier to drive.

If your P&C s were good, going to a 2.4/2.7 crank and rods gives 10.3 cr
Going to 2.4 S pistons only gives you less than 8.5 cr because they are 8.5 on the long 2.4 crank.

Actually, the 10.3 number theorized by changing the stroke is extremely misleading.
Over the years we've discovered that the 2.2 "S" (9.8:1) static compression is actually closer to 9.4:1. By changing the stroke the resulting static compression is closer to 9.9:1.
