John, I have come across many of your posts on this subject, thank you for your advice. When i get closer I'll likely need more.
Dave, thanks great advice also..
My Type 4 is set up for upright cooling. Est. 140 HP, has already been bench run for a 1/2 hour.
I want to use a 911 oil tank [external filler cap too] and two oil coolers, one in each fender like an R, thoughts?..
BTW my 912 "R" tub is coming along nicely.
