Can someone explain to me how a distributor can be installed 180 degrees off. I'm still struggling with getting my motor fired up. I double checked the TDC timing mark. Rotor points to the #1 terminal, firing order is set properly. The engine just won't run. Fuel and spark looks good.

The crank turns twice for every one revolution of the cam. Having the timing mark on zero doesn't mean #1 cylinder is at top dead center for the compression stroke. It could be on #6. Disconnect the coil, and pull the number one plug out and put your finger over the plug hole opening. Turn the engine over by hand or with the key (one quick click at a time) until the compression pops your finger out of the hole. Now you are on compression stroke. Turn the motor until you are at about 10* BEFORE TDC. This is a good starting point for a V8 Chevy. Line up the distributor with the number one wire and she should go.
Hope this helps.

....or before you pull the distributor, you can swap #1 with #6 and change the firing order accordingly from the "new" #1 and if you are truely 180 out from where you think #1 should be the engine should fire up.

Well, I got the thing started last night. I was turning the distributor the wrong way to advance my timing. What a dummy. Anyway, I turned it about 1/2 and inch counter clockwise and it fired right up. I had a few small coolant leaks so I shut it down fairly quickly but it seemed to run very smoothly. I don't have the exhaust hooked up yet so it was loud as hell. Once I get the leaks fixed I'll break her in!! thanks for the help!
