Paying for the machine work tomorrow.

I balanced all of the pistons to .001 grams, (385 grams), balanced all of the rods big ends, polished the crank and oil journal, honed the block, hot tanked the block, had the head surface finished.

Lapped the valves in last weekend and all so, hopefully it'll be together soon!

I am not using factory EFI - using MS2/E full standalone.

No I know someone above you asked what EFI I was using.

I got some updates!

Dropping it in as soon as possible!

Update time!

I just got back from my buddy Jay's to pay da' man. Motor looks really good - completely degreased via hot tank and such. Crank is cleaned up and Jim is going to polish the oil journals at assembly time - Jim is offering to put it together and he's experienced so I am going to go ahead and have him do it. I will be stopping by to check out what gets done, so once I start phase 2 (or 3?) of my car I can have an idea of good practice.

Anyway, here are the pics:

Crankshaft is all cleaned up/polished - jim is going to polish the oil journals even more to insure no catching on the new bearings.

Block after hot tank and hone (stock hone for 84mm pistons) - will be powdercoated a high shine/bright silver.

Rods, dynamically balanced to one another both ends with pins, to insure correct bob weights and all

Pistons all balanced in and soda blasted clean of 200k miles of carbon - check out the condition! (the dirty spots are from letting the piston air dry from being washed with water - going to clean again jays part washer rather than water).

That's the update!
