I had the same problem with mine, it was the pick up coil. Better yet, if you have a spare dist., try it.

Mine used to do that, pretty sure it ended up being the distributor.

IMO, if it is a bad pick up coil, you are better off to replace the entire distributor.

$10 in parts and 20 minutes to change VS $100for a new distributor.

How is replacing the distributor better????

Well, you still gotta pull the distributor either way and this way all new other parts go in plus usually you get a higher voltage coil and a module that may be better than stock.

yup and easier..  you are getting a lot more with the distributor including piece of mind.

where do you get the pick up coils for 10?

Last one I got was at Napa, back in may or june of 2010

Distributors have a minimum of parts.  Buying a new one is a waste, since you are paying for parts that do not wear like the Housing.

And TexasRed, as for the coil, not really at least in my case....  TBI dist. do not have an internal coil.  It is external, and mounted on the Intake Manifold, so you don't get a new coil unless you buy it separate.

topp, some stuff does wear out though, like bearings. if he's got a '76, he might be better off getting a whole new distributor as it may be time for a rebuild of the stocker.

you're right, mea culpa on the external coil ones.

but I agree with you. it doesn't make much sense to throw parts at something if you don't have to.

AFAIK there are no bearings in a Distributor....

I hate problems like he's having though....
I had a few weird ones when I got my K5.

Never threw parts at it though....Thats a waste of time money and nerves.....

New HEI distributors can be had for pretty cheap nowadays.

^ just an example, not an endorsement ^

While I agree with topp's philosophy, in this case you just get a lot more new parts for a little more money to save yourself some trouble in the future.

Grim,

That Dist would work for the PO (although I hear bad things regarding those clear Dist's).

Not for my 87...
Cheapest I could find is over 100, since I have TBI and the External Coil....

Apples and oranges ;)

I haven't heard anything bad about the clear caps, I just don't prefer them. I like the bright red MSD that I have. When I first got the truck going I used what was in it until I could afford a new dizzy, and then with plugs, beefy wires, a recurve kit, and no more ESC garbage I had all brand new ignition system. Some of these cheap new HEI distributors are pretty good I'm sure, and when you total up new cap, rotor, module, coil, and everything it can be cheaper just to swap the whole shootin match all at once.

If you're really on a tight budget though, obviously just replace only what is needed to keep it running. Still haven't confirmed a bad pick-up coil......

If your motor is mostly stock, you probably won't see alot of improvement over a stock intake, but I like the Edelbrock EPS intake. I use the 2701 with a squarebore Holley. If you are using the q-jet you would want the 2101. For most applications the stock intake flows just fine though.
