Great information, thank you Don.
Dealing with more of the V4/V6 motors now so still getting familiar with the different production run varieties.
I will say the 60 degree powerheads are slick in that you dont need to remove from the exhaust housing to do internal work (i.e. manifold is not in front of the crankcase).
Well, I guess it is possible to do internal work on these engines without removing the powerhead, but I don’t recommend it…
