Assuming that we are talking about a stock GM HEI here ...

I suspect that you may have done the same thing I did ... washed it out in varsol and blew it dry.

It went from being a slightly grungy working unit to a squeeky clean paperweight. (D-Oh!)

The important thing ... if that new engine doesn't fire right up, stop cranking it, and buy a replacement distributor.

Check an make sure you put the rotor inside the distributor. Next replace the coil.

Re-connect or replace all ground wires.

Just went through something similar on my nephews 51 Bus Coupe with SBC/auto combo that I gave him. Completely new powertrain, and we just finished a rewire of the entire car. It ran fine before, and even during the rewire; after we finished, it would'nt start. We tried everything, checked and rechecked everything. Even swapped in a NEW HEI distributor. Finally, we replaced the brand new spark plugs with another NEW set; it fired right off. I've NEVER had anything like this happen before, and still don't quite believe it. I've never been so frustrated.

I guess you've got a pretty new paint job on the block. check the distributor and make sure it's grounded to the block, you might have to scrape some paint away.
