OK, call me paranoid.
This is my NEW cam.
The original cam was scrubbed due to improper break-in.
The dissimilar wear, and even the fact that there IS any visible wear pattern on a cam with only a few hours on it ... quite frankly SCARES me!
The pics below are in the correct order, from the front of the engine to the back.
Should I be concerned?

So now the intake is off.
Just what the ____ is that technicolor mess in the driver's side rear water passage?
More traces of dried antifreeze corrosion on the intake ports?
I'm truly puzzled by this gelling and corrosion.
The block has been dipped
The radiator is BRAND new
The coolant was freshly installed several years ago (2008?) ... but this truck hasn't turned a wheel yet!
Yes, I had used the stock Felpro Gasket (MS90240-2) which might not be correct for an aluminum intake with no exhaust cross-over. I have reordered Felpro Performance # 1210 today.

Well call it good luck or bad ... but I finally got around to pulling my very new Edelbrock RPM Air Gap intake off today with intentions of re-sealing it.
The first thing that struck me as being odd, very odd, was a WHOLE bunch of crud in the thermostat housing.
And on the thermostat
And inside the intake below the thermostat ... gelled antifreeze.
After cleaning up the thermo housing with the pressure washer, I discovered that it had corroded to the point there was a hole right through it!
Wait, it gets better ....

I forgot to add the pics of the misaligned cab mounts. I have jockeyed it around a bit since, swinging the back of the cab to it's proper location ... which helped a bit ... but still out that 1/4 inch.

OK, so now the firewall has been butchered up, and I can now slide the cab forward to where I think it needs to be.
Darn it ... it's REALLY hard to move it forward! I'm jacking the cab up with the floor jack, and now it moves quite easily. Dragging on the bell-housing? Nope, looks like plenty of room there ... as it should be, seeing as how the bolt-up was likely the same as the inline 6.
So I got my trouble light out, checking from a bunch of different angles. There it is ... right where the firefall meets the trans tunnel there is a seam and it's resting on that!
So now i'm thinking I'll have to modify the trans tunnel as well, extending it at the same height from the seat base to up a little higher on the firewall. (area in red)
I suppose this mod would have been nessecary, even if I had gone with an SBC, right? The TH400 must be a little taller than the old 3-speed M/T ?
To top it all off, it's beginning to look like my buddy welded in the floor patches slightly out of place. No matter how I shift the cab from side to side, the bolt-holes and frame tabs are out approx 1/4 inch. I may be able to elongate the holes in the cab mounting bracket enough to compensate.
