I recently bored a 413 .030 and am having trouble with it
overheading.. Im on my 4rth radiator and 3rd fan. No matter what I
do, idle or down the road, Im running 205-215degrees. Used a mechanical gauge,
mark 8 fan, 3 water pumps, 2 copper and 3 allum new radiators, Im at wits
end.. any ideas from past experience? Im starting to wonder if the .060 was
too much… any comments?
