Hi All

just had the valve stem seals done on the 429 with the passenger side head coming off due to a broken bolt.

That is all done and back together.  Now one problem leads to another.  The engine will not idle

or idle adjust as it should.  If I screw the main large idle adjust screw in on the carter the engine still

runs - if I turn the drives side smaller idle air adjust screw all the way in the engine does not stop.

There is a noticeable flat spot right at bottom of idle on take off and the engine just is not right at least

at idle.

Is this an indication of a vacuum leak?  The problem is still there if the PCV valve is off and blocked,

same with other vacuum lines.   Hope that makes sense and I can get some advice.

Great to hear John. If your vacuum advance is original to the car I'd test it with a small cheap vacuum pump. It shouldn't leak down at all. My car ran fine but the vacuum advance was no longer working and was leaking. It ran even better with the fix.

Oh geez, it looks like Tony was correct..... we'll never hear the end of it now. :-) LOL

where do I find a new and better motor?

Posted by john kilbourne on May 24, 2018 at 11:43am 11 Comments

My '64 convert is getting better, but the engine remains questionable. Starts and runs well enough, powerful, but I think I hear a main bearing banging, the balance is not great and I'd like to upgrade to fuel injection if I can.

Are there dependable remans available of good quality? Are new crate engines available? Will more advanced engines from newer years fit?

Also, please, the diff ratio is quite high, lots of RPMs compared to today's cars. Are there diffs with lower…
