An oil cooler works well because when your engine is cold, it won't cool. When your oil gets hot, ambient 110˚ Texas air hits 300˚ oil and efficiency finally has a chance to work because of the drastic difference in temperatures. - Dave
I blocked the crossover port and no exhaust goes through the manifold.
I did not weld the riser open but I will do that at the shop this weekend.
I have never run a separate oil cooler. Where do you pick up source for the oil?
All of cooling system components are new or in working condition so, based on your Thunderbird driving through the desert comment on another post
, I thought I may have a bunch adjustments, that combined, make the bird hot.
I would prefer to not make any changes (no shroud or flex fan) so working through this is good. That prior post got heavy with extras so having this one address it directly is good.
