Compression Ratio, Will I be able to tell the difference? Options

[sdoolin]

Rebuilding(ish) my 2056. On my first build I was able to achieve a compression ratio of very nearly 9.0:1. With this build, I am having to add .020 spacers below the jugs to get any measurable deck height in the jugs. I am calculating a compression ratio of 8.6:1.

Will I notice the loss in compression ratio?

Engine went in on Friday. Easy peasy. After I poured a celebratory Bourbon, I realized I had installed the moustache bar incorrectly. Easy enough to fix. Attempted to start her up today. No go. Triple checked everything. No vacuum leaks. Fuel pump is working, carbs are getting gas, plenty of air, so it must be spark. Yep, dizzy driveshaft installed 180 degrees out.

My 40 years old Haynes manual (for a bus) says to install the dizzy driveshaft such that the "small" side of the slot is on the left hand side. Well, the left hand side, to me, is the drivers side of the engine. The Haynes manual should say to install the dizzy driveshaft such that the small side of the slot is on the left hand side of the engine when approaching the engine from the fan side. Anyway. I fixed that and she starts and runs. Not well. but the carbs need to be synched.

The worst bit is that my oil pressure light goes out for a short bit, then comes back on. It has done that about three times so I have shut it down and commenced heavy drinking.

I'll find a way to put a proper oil pressure gauge on it before I start it again. Sheesh. She is really putting up a fight.
