Haven't fell for that since I was about 14 years old.

whoa...

Settle down there fella. You aren't being very nice to anyone here.

Hey MrGoodass (wrench with a "H" addiction) How can a V-8 engine with the wires mis-routed spark plug wires run smooth at an idle but miss under a load? This should get interesting, get yourself some serious carbs for dinner, you'll need them.

This isn't totally true. A partially clogged filter, even a stone (brass) filter, will sometimes let the bowl run out of fuel on a longer pull than normal (like a hill, moving that big thing).

And an egr valve stuck open can also definitely cause a very lean condition, which would also cause power issues.

Go try and turn some other thread into a pissing match. The man asked for ideas on what the problem is with his vehicle and I'm trying to help. I really don't give a shit about your 'stayed at a Holiday Inn last night' knowledge.
Personally, my money is on whatever Sauto says.

Did 75s run Points? **** points. If it has points check those. As those wear they can affect timing.

On my irrigation engines I was able to get an electronic ignition aftermarket. I’d imagine something similar is available for the bigger motors.

LMAO :clap::clap:

I say load the thing up with a bottle and see if it helps. It'll either fix your problem or give you the prefect excuse to buy a new engine!

Let the little man who's named after his little cock fix it for you. When Andy is dead and Alex11 is having his number hung on the ring of fame your ****ing truck will still have a vacuum advance that in not doing it's job...

Most did but it's in a breadmobile so maybe not... if the guy put a new distributor, coil and, wires in he should know....

with a rag sticking out of it???

I think this is the direction I need to go first. I've played with the points ad nauseum and considering that I have a few more issues starting and running during the later parts of the season due to colder weather, this will help eliminate those problems and allow me to identify any other areas not previously addressed.

Geez, GD, you have extra $$ for a new engine? I don't!!

That's just it. I've replaced everything BUT the points and considering that lack of experience I have with older motors, I'm just looking for some assistance because there's no doubt that I'm missing something simple that's keeping this engine from performing like it did back in 2009-10.

For me, the win is that it's starting and running consistently again, but I'd like to get about 10 more years of tailgating out of this vehicle before I'm done with it.

monty monty monty

what is base timing? what timing at 2500 rpm?

Do I need to explain timing to you?
