Technical 327 dying in gear

Yep... come up to a stop and she idles like she should with the thumper cam...Like she's slobbering on herself ..

 

Well she started dying on me again.... I fixed her good this time though.... I pulled the trans yesterday and installed a 2500 stall converter... That was my problem all along! ... .Thanks to everyone for their suggestions and thoughts....This place rocks!

 

So how do you like the looser converter with the big cam?
Bet it wakes right up and pulls. Make sure to fiddle with carb mix, acc pump (if adjustable) and timing curve to get it optimized. You can probably add a couple degrees of initial timing since it won't load right off idle, but you may need to trim down total with the bump.

 

In my experience in can become slightly addictive having a vacuum gauge mounted in your car permanently, or even semi-permanently. Get one with a fairly large, easy to read dial face and a wide sweep. Mount it inside the vehicle some place where it can be easily read while driving. Make sure it's connected to a source of full manifold vacuum, not off-idle or ported vacuum.

Find out the vacuum rating that your power valve operates at or how much vacuum it takes for the power pistons to pull the metering rods down to their leanest position. Figure how much vacuum it takes to actuate the distributor vacuum advance. If you've got an automatic transmission, look at the vacuum difference between idling in park and in gear. Then go out for a drive and regularly glance at the vacuum readings under different driving conditions.

Note the reading while driving at a steady speed on a fairly level road. Look at what happens when you slightly accelerate or de-accelerate. Check the gauge when you're pulling a loaded trailer or pulling up or down a grade, or while pulling out of your lane and passing another vehicle on the interstate. Watch the vacuum again when you pull back into your lane in the slip-stream behind a semi-trailer or large box-truck. See what happens when driving at a steady speed with a tail-wind or when driving into a head-wind.

And all the while, you''ll know exactly when your power valve is opening and closing and when your distributor is increasing or decreasing the vacuum advance. It will also make you realize exactly what's happening at a given vacuum reading at idle speeds while sorting out your tune-up.

 

I appreciate it...... Yeah she runs like a scalded ape now...... Ill tinker around with the carb and timing when I get a chance

 

Glad to hear. Remember that rich is safe, less timing for the same result is better, and delivery of good fuel and good electrical (grounds too) will fix a lot of little issues.

 

It must have been right on the fence between a stock and a stall converter. Most of the time what the cam maker says, you can bank on it.

 

Had the same thing happen to my 41 Chevy and posted about it here on the HAMB also. New B&M stall converter did the trick.
