just got me a '67 Barracuda

The odometer reads 84,200; there's no 100,000s on the dial.

It ONLY runs if I have the timing jacked way up, to about 20 or 25 degrees BTDC. If I try to turn the distributor so the timing mark approaches 0, it dies at what looks to be about 15 degrees BTDC.

Another guy suggested I do a thorough check for vacuum leaks, first. Reason being is that if I close the choke valve when the engine is warm, instead of dying, it revs up and smooths out. I've sprayed around the intake manifold, but not very thoroughly, 'cause I didn't want to ignite the stuff. But would a vacuum leak account for the bad timing?



Nice car!

All most sounds like the dist cam drive is not in right and your tming is off. It has to be put in just right. If it is a few teeth off it will make timing impossible.

Good luck on your build.
