Are there any gotchas on the 3100?

[oleman]

I have our M 3100 ready to go back together. New pistons have been fitted to a professionally bored .5mm OVER and honed block and professionally mounted on rods. The block was decked .006 and the heads cut .008.
Crank was cut .010
I have assembled many engines but this is my first 60v6.
If anyone out there has totally assembled one recently. are there any issues I should be aware of?
Appears to be a simple assembly unless I am overlooking something.

If you've put together a smallblock you've put together a 660. Its all the same shit.

Just use a damn torque wrench.

its pretty simple. its amazing how much it goes together like a sbc.

basicly, as long as your machinist did his job, it should fall right together.

if they still use an o-ring in the rear main bearing for the oil passage, dont forget that, or your not gonna have enough pressure.
