is it doin it more when it's damp out? That would point to a cracked "dizzy" cap or a wire problem....Neil

wow, good luck with that one, oxydized cast aluminum can be a bear to get unstuck especially when it is inside steel ya can't heat it because it grows more the the steel around it. If your choice of oil doesn't help try some weak acid like COKE,,,just a suggestion...Neil

Just soak it everyday with penetrating fluid and it will eventually soak it..

Diesel fuel works well too.


Curse the last guy who took the Disty out and never put any anti-seize on that part of the shaft,

It will come out wihout damaging it if you are patient with the penetrating fluid and not using something to turn that make break the cast metal

You can try tapping the Vacuum advance housing a rubber or plastic mallet occasionally but don't pretend it's a 8 ft post you are trying to hammer into the ground

When I said patience with the penetrating fluid I meant like let it sit a few days to let it do its work

The good news is that distributor can be found used in any 351M/400,460 at the wreckers.
Unless you buy new that is

If you mean that little piece of steel tube.... that can come out with a spoon chisel an hammer.
Those get replaced all the time and are always in stock at parts houses

Remember... you're parked at the right place ....FTE

The picture title is 77 distributor. Is that because it is in 77 pieces? Hammers are amazing tools aren't they? Theres nothing they can't fix (or destroy).

The Camshaft.



That probably broke trying to get the distributor out


TDC arrive twice in each cylinder.

You need the one just as the intake valve on the number 1 cylinder closes

I assume you didn't mark a spot that the rotor was pointing to before the smashing began ?
