Nice GMPP timing set

Block ready for trip to machine shop.  4-bolt main caps will be installed.

I drill my own small oil holes in the oil galley plugs to cool the timing set with oil spray like factory.

New water pump gear.

ARP cam bolts

GMPP extreme timing set.

Mocking up #1 piston/rod to degree the cam.

Bearing clearance .0021" with Clevite HN standard size bearings.

Piston is .006" in the hole

Camshaft is 106 deg. ICL exactly as per cam card.

Rod shoulder bumped the bottom of the cylinder in this spot.  Took everything apart and ground for clearance and cleaned with soap and water.

Was meaning to make the rear main bearing a bit tighter so I took this opportunity to do a mix of standard and .001"

Top ring at .020"

2nd ring at .018"

Rod bearings at .0020 to .0021"

The oil pump just barely touched the main stud.  I clearanced the pump just a bit.

Melling 10552 oil pump.

Mr. Gasket .026" head gaskets.

I measured the chamber volume.  I'd say this is give or take 2 cc accurate.

Cleaned up the ARP head bolts.
