My stock oil lines to my filter and cooler on my 6.2 MPI are 3/8". I plan to replace them with 1/2" fittings and #10 lines (I have new coolers).
Does anyone have a good source for both the block and remote filter (single) adapters?

Also, would it be better to get oil temps after or before the cooler?
I'm trying to wrap my head around this one and I'm coming up empty!

Canton makes good stuff. Temp before the cooler IMO, but you'll get both sides of the story here.

I take my temp reading from the pan.

maybe you should have 2 temps. how hot it gets and how well it is cooled...
