Just a quick question. I had overheating problems on a prior engine that was bored out 0.060. I have two possible engines I can use, one is an early 440 that cleans up at 0.040 and the other is a late 440 with stock bore that would be 0.030.

I'm partial to using the early 440 at 0.040 bore, would this extra bore factor into any scenarios of overheating?
