If you need to rotate the oil pump shaft to get the distributor to drop in, a nice long screwdriver will do the trick. Be aware that the distributor will rotate when it meshes with the gear on the camshaft.

That cheap aftermarket ignition trigger system he's running is simply horrible. In addition to being unreliable and offering no performance advantage, it will mis-clock the rotor to the distributor drive gear, causing the distributor to be a "1/2-tooth off." You then have to remove the distributor, removed the drive gear, and rotate the drive gear 180 to compensate for the mis-clocking caused by the cheap-*** "electronic" ignition system. I have shoe boxes full of those that I have removed from customer cars to solve ignition problems. He would be money and effort ahead by throwing that system in the trash can and installing a good set of points and condenser - it will then make it possible to "static time" the ignition system and set it up right.

Still working thru the paperwork you sent me this morning @lars .

The distributor was on there when I got it. What would be a good recommended replacement brand?

I would return it back to what the car was born with. Points. There is nothing wrong with a well maintained points distributor. Points will get you home. It may run shitty but, it'll get you home. You can find OE tach drive Corvette distributors on Ebay. Or get the parts needed to return your current distributor back to points.

There is nothing wrong with your distributor. It's the "electronic" conversion that's been done to it that sucks. Yank that junk trigger system out of it and put the distributor back to its correct, stock configuration. Use NAPA/Echlin points CS786 with condenser RR175. You'll probably need a new lead wire part number LW72.You'll also proibably need the hardware to install it which is Balkamp part number 665-1133. Set dwell to 30-32 degrees. The points system will be reliable, and will allow you to correctly clock the distributor as well as setting static timing as outlined in my papers - this will allow your engine to fire up instantly after installing the distributor correctly.

Thank you everyone! Finally got it idling. Not perfect, but the first time this thing has idled consistently in 25 years.

The main issue was the timing. The Service manual had a great chart that helped me visualize what was going on. That tied in with Lars papers got me over the hump.

I also put a new carb filter in it last year and it already clogged. Probably crap in the lines as the tank and pump are new.
