Exhaust system question
At what point do you worry about have a water reversion problem in your exhaust system. Stellings headers and tail pipes. Water enters the tail pipes about 16 inches away from the header were it meets the tail pipe.

No way to find overlap at seat without those #'s.

40* is a lot of overlap and likely to revert water with wet exhaust. Most marine cams are 20* or less.
It will also depend on how many cubic inches you have. A cam that reverts in a 502 might not in a 540 and will be mild for a 572.

cam
Thanks for the input. Not looking to change cams or anything just trying to avoid a problem in advance. Was not wanting to have to change my tail pipes because they have built in mufflers but it looks like I don't have a choice all good.
