Nearly all machine shops will have a bore gage set. So you could either go to a near by one and make a deal (case of beer, bottle or something, etc.) with one of the machinists to come over after work and measure the bores. It shouldn't take him more than 30 min to measure.

Andrew, sorry I missed the pull party. Looks like you had plenty of help though.

What are the other "While Your At It" items on your list of things to do before the install?

IMHO, take your time, I'm sure your wife won't want you doing this again for some time. We only have 3-4 more weeks of hit and miss driving days remaining. If I were you I would keep that engine out until February and do everything you can think of to make it bulletproof since you are trying to hit the 500 rwhp objective.

Give me a call if you need anything ... talk to you soon.

coolant resevoir - maybe
Clean the engine bay
Upper A-arm bushings
Steering rack busings

Engine
Oil pan gasket - re-install w/ sealant
Head Gasket
Cam seals
Valve train stuff - no clue on this...
Exhaust gaskets
Timimng belt
Water pump inspection (w/ replacement?)
Oil pump inspection
Front main seal?
Rear main seal inspection
Chain Tensioner pads

What am I missing?

When the guys at Thompson's measured my block, they used a periscope style guage, but it was different than what I've previously seen. It was shaped like an L and looked pretty old by the solid wood case it was in. The base of the L has a rollers on both ends. The measurement was taken between the two rollers. The rocked it back and forth both end to end and side to side to measure roundness. It took all of about 5 minutes to do all 5 cylinders on my engine.

I used my digital micrometer and it measured 99.6mm IIRC - same as the other cylinders.
Andrew, all you need to do to check for ballooning is to measure the bottom or middle of the bore, and compare it to the measurement at the top of the bore; they should be the same.

I am sure there is no need for new rods.

Thanks Big Dave... I'll put them on the list.

Motor mounts were done last year and replaced with sollid mounts, but I will certainly inspect them.

With that restriction, now you can't ask Dennis or Stan.

Ishihara-Johnson scaper, oil pan spacer, check the bearings, replace any suspect TB tensioner system components.

Replace upper A-arm bushings. The upper A-arms are easily removable now that the motor is not in the way. Nearly impossible otherwise, although I have heard people have managed somehow.

Awesome suggestion! The bushings are not terribly expesive IIRC, but are a royal PITA to replace because of the upper A-arm removal... but with the engine out, it's a no brainer! Added to the list.
