If the plan is to use little cams like those there is no reason to put a much bigger crank in the engine. 4” is ok, but with those cams it won’t run a lot better than the 3.75”. You”ll end up dropping the compression more on the bigger cranks to keep the engine happy on pump gas. It offsets a lot of the gains with the bigger crank.
