It seems to be hit or miss. My old engine (a 360) wouldn't allow over 20 before it would kick back on the starter. My new engine (a 408) has much more cranking compression (180 vs. 150 on the 360) and yet I can run 24 initial with no starting woes. Same starter, battery and wiring too. Go figure.
(Why the heck does this board put up a smiley face where the number eight is supposed to be???????)
