Just had the 327 out to spruce up a few things. Bought a rebuilt distributor and am having problems getting it to engage oil pump driveshaft. I've used an oil pump priming tool and have pressure and yes, the gauge works. Have an Edelbrock manifold on which the distributor boss is lower than stock. With the original dizzy, I had to add spacers. When I first tried to start, no pressure. Took out spacers, had pressure, but couldn't get it started and flooded it. Fixed that, made sure dizzy was flush against boss, finally started after first running down the battery and no pressure.
This is just one of a number of things that seem to be out of the Twilight Zone on this project(my fan belt shrank while it was out. WISH I was making that up, but I'm not.).
Any ideas appreciated.
