why do some diagrams show the wiring like this



and some show it like this:



I did it the second way, with the rotor pointing at 1, and the wire on the cap post pointing at 1, i am non HEI points style

Maybe its time for a compression test.

healthy & repeated backfiring thru the carb is one of 2 things:

1. A spark plug firing way too soon (like when the intake valve is open) - wires not routed properly.

2. A intake valve not closing, or open at the wrong time.

At this point, you need to make sure you are getting good even compression on all 8 cylinders. This will also tell you if the cam is lined up properly.

Do a compression test at this point.

ok, thanks

got a guy from work who is pretty good with all this stuff swinging by tomorrow afternoon to help check it out, we will be doing a compression check and checking out the distributor so make sure everything is okay with that, damn this is frusterating, everything i have read says everything i did was done right so far as i can see, hopefully a fresh set of eyes will help, time to forget about this motor for 24 hours and play the new call of duty, lol

Good idea, get a 6 pack too. I like Red Alert 2 when I need to take a break.

lol, for sure, never hit the store after hitting game stop today, so it is a vodka and rootbeer night will start over after work tomorrow... where is that reset button for the last few days, lol

You've heard this before I'm sure, but it really makes no difference what terminal is #1 as long as the firing order is correct.

You can reconnect the vacuum advance. It isn't likely to be the problem, but the engine needs to have plenty of advance, so hook it back up!

A points-type distributor can give you all sorts of problems. Has the dwell been checked? What about the plugs- they should be fresh, too.

Curious to see what the compression test tells you.

[evilbeef54]

compression test tomorrow he forgot to bring the tester today, lol, will post up results, however he did stop by and checked out the dizzy and thinks it is pretty jacked, the vac advance can is stuck and doesnt want to move, it looks like it is pretty far out of adjustment and pretty dirty, i am sure i can just replace the can and clean it up, hopefully this is what is leading up to all the issues, gonna try a different distributer tomorrow and see if all is solved.

Sounds like an opportune time to upgrade to HEI.

[evilbeef54]

thought about it, HEI doesnt look like it will fit with the tight clearance on the firewall, however i found a local guy that has a MSD pro bilet, with 6a box, wires, and upgrades for great price
