Something doesn't feel right.


A tooth missing in the water pump gear.  I have a few LT4 extreme in my drawer but I'm not sure if they are compatible with stock.  ??


Lifters from Lance's other motor that is now in Nabil Guffey's shop.  These look like LS7 to my eye.  Slightly different pushrod seat and shape at the side oil hole.


We agreed on going to an LT4 extreme timing set.


The water pump drive gear is included in the LT4 extreme set.


Degree of camshaft gives 109 deg intake centerline.  Exactly as the cam card!

Nice looking LE heads

experimenting with paint.  The block will be black.


More photos of the bottom end prior to installing oil pump and oil pan.


I had some delays testing the oil system.  The Melling 10552 oil pump felt like it was binding.  I will return it.


New oil pump in and oil system tested sat.
