as you know I fooled around with the diamond pin block, but in my own testing I can see no advantage over the cupped base temp wise. I am no longer going to make those because of the work involved with no real gain. I have one of my diamond pin blocks on my rig now and it may actually be running a couple of degrees warmer than my old V6. I am cleaning up and polishing that old V6 and it is going back on when get my Blood Iron this coming week and finally make the switch to dual core.
Hehe, dual-core eh? Pretty fancy...
After thinking on it, I suppose that the air traveling over a golf ball is travelling much faster than the water in a cooling loop, so really it would probably have to be at 500psi or something screaming through the loop to measure a difference in flow.
Either way though, looks great as usual. I wish I had a mill in the garage; I have to drive all the way across town to use the one at the shop.
Kinda sucks when you drive a truck and gas is $3.96 a gallon.
