Trick Flow rockers

This is the cleanest head gasket I have seen.
|
|

Nice clean engine. The block goes out for
bore/hone/square-deck/main stud align hone.
|
|
|
|
|

Intake manifold sent to LE for porting. These are photos for my
memory when putting things back together.
|

Time to clearance the bottom of the block for stroke.
|

Sharpie marks the spot.

Callies dragonslayer, 3.75" stroke.
|

Block cleaned and ready for main bearing clearance measurments.

Another view of the crankshaft.

Checking piston deck-height. All pistons at .011"
(in-the-hole)
|

A few rods were too close to the block.
|

A little more grinding/clearancing.
|

Block is all cleaned and ready for final assembly.
|

I saved the installation of cam bearings until now just in case I
had to grind more for rod clearance.
|

Callies Compstar rod bolts torqued to 75ft-lb and .005"
stretch.

Camshaft installation. One snafu was that that cam-pin was
too short to drive an opti-spark. I pulled it and inserted a pin
that was taken from one of my used camshafts.

New sprocket for the water pump drive.

Cam card calls for 108 intake centerline and I found it at 107
which is within my goal of being + or - 1 deg.
