I'm confused about your original plugs, at the start of this thread you said they were 26's, now 62's? Maybe a typo? Regardless, I'd go to the 44's. My blower motor would always start first revolution, with a super hot MSD. When I flooded it once it wouldn't even fire. I pulled the plugs, cleaned them with starting fluid, dried them and it fired first roll over. I've fired the motor with a ton of fuel introduced, but once it flooded..nada.

my bad, 26's were in it when i bought it, went to 85's no luck so went back to the 26's. but after pulling a plug and grounding against the header last night my spark was white with a little blue so it looks like i have an elecrical issue. the nova came with some cheesy gauges and at times the volt meter is pretty eratic, i just dismissed it as $24.99 sun pro guages being lame since ive seen that before in those guages, but now im thinking that although they might not be completely accurate that there is some kinda power/grounding issue or the tach is messing with the dist somehow. i have no idea how old the HEI is but it seems to look pretty new color wise, like it hasnt been in there for ever.

after thinking about it, shouldnt i have felt at least a minimal shock while holding that plug and grounding it, i did use coated handled pliers but im sure ive done that before and i seem to remember getting a good jolt from it.

Take a good look at the rotor. Make sure its not burned through the top to ground. PHYSICALLY TAKE IT OFF AND LOOK AT THE BOTTOM. IF IT HAS A BLACK SPOT ON IT UNDER THE CENTER ITS JUNK, BURNT THROUGH.

i pulled the tach and it wouldnt start, pulled the module, autozone doesnt test them any more and o'reillys has the load tester but no rocket scientist that knew how to use it. so i bought one any way, i installed it and when i was putting the cap back on my dist turned about 45*, when i bought the car i had the local mechanic go thru it and he timed it, i did get it to start this morning but it ran like crap most likely cuz of the timing. the mechanic had told me that the bottom gear of the dist was chewed up a bit and that there was shavings in the grease. he blamed either a cam going bad or the dist not being installed correctly. i called him this morning and of course he said he tightened it correctly and that it could be "bouncing around" and thats why it was loose? so as of now its not running yet but it seems to be close.

327 spark plug issues

If you feel comfortable enough pull the distributor check the gear on the bottom. Shine a flashlight in the hole and have someone bump the engine over to check the gear of the oil pump. If you can see them check the teeth on the camshaft too. If you see any damaged teeth on the camshaft or oil pump gear it's time to change them. If it's just the distributor gear buy a replacement, knock the pin out, but not all the way and replace with the new one. When replacing the distributor install with no gasket to see if everything fits. With it bottomed out on the oil pump gear measure the gap between the distributor housing flange and the intake. If the gap is more than the thickness of the gasket buy a shim kit and install .

Installing a HEI distributor

Here is an article from wiki on HEI distributor installation. http://www.crankshaftcoalition.com/w..._a_distributor and another one on GM HEI Distributors. http://www.crankshaftcoalition.com/w...EI_distributor Do you have a timing light with the advance knob to check the timing?

When setting engine timing and setting up the HEI you definitely need a timing light similar to this: Summit Racing SUM-G1059 - Summit Racing® Timing Lights - Overview - SummitRacing.com
If you don't have one see if a buddy has one you could borrow. You have to do these things yourself because I would hate to see what a shop would charge. Besides most of the time when you pay a shop to do your work when checking it ,you end up doing it over. My brother-in-law found that out the hard way.
