I broke'did my toy... Kenne Bell/370 rebuild
#101
Repair went pretty well but I did get a little over zealous with the wheel on one of the ports causing a slight dip that I couldn't get out. It measured .010" with a feeler gauge and straight edge. With the exception of these low spots, the deck overall is flatter now than that it was to start with. I am sure the gasket would have sealed the small dips but I didn't want to take any chances and dropped it off at the cylinder head shop this afternoon to have it decked .010. Should have it back Wednesday (which really surprised me).

I also did a little troubleshooting with the intercooler and think I have figured out why my IAT's have always been so high. With the inlet and outlet in the same end tank it should have a separator in the end tank to divert the coolant thru the ic in a dual pass method. My end tank has no separator. Water flows directly from inlet to outlet without passing thru the core. How difficult would it be to cut a slit in the end tank, slip a piece of al flatbar in there and weld it up on three sides?

I figured this was just as easy and I only had to take it one place. The Felpro gaskets are .060 thick and fairly incompressable which will space the manifold a little further out from the heads than the orings. However, now that I think about it, I hope the reduced deck thickeness doesn't compromise the rigidity of the deck and sealing ability.

I has a few boxes of goodies when I got home from work today....
-Gagatized 2.5 bar map
-longer manifold bolts (with some other misc hardware) from McMaster
-1/2" injector spacers from FIC
I also picked up the manifold from the machine shop. He ended up taking 0.015 off to get the low spots mostly out. There is still a very minor dip at the edge of the port that I am pretty sure the gasket will seal up. It's raining and manifold is still in the Tahoe so I will get a pic of it tomorrow.
I did some exploration on the intercooler and started on the phenolic spacer.
Evidently the intercooler is a dual pass with a separator in the tank dividing the ic top to bottom rather than side to side. See the marks in the pic below for how it is divided best I can tell. I don't think the bars are separated though. You turn the ic up on end with inlet/outlet at the bottom, fill one side and water appears nearly instantly on the other side. At this point I am wondering if the flow direction makes a difference on the coolant's heat absorption.
