23Dec05 Called Dick at Stroker Motor to discuss the compression ratio issue with him. He's going to 'cc' my heads next week and verify the chamber volume. The cylinder head combustion chamber volume will determine what the ratio will be. If I remember correctly, the chamber volume is around 62cc(a stock head is 54cc). If that's true, the new pistons will have to be returned. Luckily, SRP makes a set with a -16cc dish. Spent the rest of the day cleaning parts and the engine compartment.
15Dec05 Made a trip to Stroker Motor again today with a set of rings and rod bearings so that they could be weighed for rotating assembly balancing. My cylinder heads are complete! Everything checked-out OK... even the valve springs.
16Dec05 Decided the pistons were not worth cleaning up and reusing. Ordered another set from Jeg's.
21Dec05 JE/SRP pistons arrived today!
22Dec05 Delivered the new pistons to Stroker Motor today. Stayed up late playing around on the JE/SRP Web Site and realized that the new pistons -- and the pistons I had been running all along -- could potentially push the static compression ratio much higher than I had intended... to about 11.25:1. in fact! I was aiming for 10.0:1. I wouldn't be afraid of running 10.8:1 to 11.0:1 on the street, but I'm still planning on using a low boost supercharger(PowerDyne) on this car so I'm shooting for 10.0:1 max.

12Jan06 Went to Stroker Motor today to get some pics of the rotating assembly being balanced. Assembly balanced to +1 gram at the snout and 0 gram at the flywheel.
27Jan06 Block and rotating assembly are complete. Went to Stroker Motor to pick-up parts. Planning on assembling the shortblock this weekend!
2Feb06 Ordered an ARP Main Bearing Cap Stud Kit from Summit. Ordered a set of 37 lb./hr fuel injectors from Racetronix. Short block assembly is on hold until the stud kit arrives.
3Feb06 Main Bearing Cap Stud Kit from Summit arrived today after ONE day!!! Amazing! Anyway, guess I'll be assembling a short block this weekend.
4Feb06 Assembled the pistons to the rods and File fit the piston rings. Installed the pistons in the bores. Discovered the one of the main bearing cap studs interferes with the dip-stick tube. I'll have to get a shorter stud from ARP Monday.
6Feb06 Called ARP about the main cap stud. They suggested cutting the stud with a cut-off wheel to shorten it. Ummm... I'm not gonna do it! Called Dick at Stroker Motor. He said that he had the correct length stud and that I could come down and get it. Whooo Hoooo!
9Feb06 Made a trip to Auto Zone and purchased a timing cover gasket set and a Teflon rear main seal. Placed an order for a pair of cylinder head gaskets and an one-piece oil pan gasket.
12Feb06 Went to Auto Zone and picked-up the head gaskets, and oil pan gasket. Got a rebuilt water pump from O'Reilly's. Installed the water pump drive gear. Installed and degreed the camshaft-- it came in PERFECT at 110 degrees! Installed the rear main seal, Installed 3 new seals in the timing chain cover and installed the cover.
