Trouble installing Langdon HEI Dizzy

[Plymouthy Adams]

I would wager a thermostatically controlled asymmetrical fan would prove to release more ponies...again..set the dyno baseline on each and all mods before and after..

 

I guess I could put a set of Nike sneakers on a elephant and make him a basketball star...

Don, I have no reason to dispute with you, lol, however I will categorically state that the Langdon HEI dissy that I installed made a huge difference to the ease of starting and general operation of the stock engine in my car..........horsepower increase?.......maybe?......but definitely better and quicker starting, smoother running and definitely worth the money for me......for others....that's their call.........regards, andyd

Andy...as for ease of starting....overall maintenance and long life of spark plug as the voltage from the coil will not vary...yes..operationally..the performance is much greater..and as the wear is now only that of secondary wiring and plugs..longer tune up and the feeling of better performance is there..but as Don says..a fresh tune up with point and condenser will also net a big improvement over worn ignition parts..I believe that is the point Don is trying to make..the tell of the dyno before and after has not been entered into evidence, that is point number 2 of his talking paper..

In terms of my particular project, I was also highly suspicious that my "standard" dizzy was in need of a major overhaul and recalibration. For not a lot of extra $ I decided to move to the HEI.

 

For me I enjoy mixing snippets of modern stuff to the car to make it work better for me and what I want from it.  These items include, radial tires, widened rims, 12V electrics, electric wipers, Ford diff, modern driveshaft, indicators, remote brake fluid reservoir, volt meter, alternator, alternator warning light and now HEI dizzy. 

 

In terms of better performance the HEI gave me that, but I do also recognise that an overhauled/calibrated standard dizzy could/would also have provided the same improvement. I guess for the future I am banking on the electronics in the HEI being less on going maintenance and a more stable ignition platform than the old points/condenser system. 

 

I may be different from others in that I have a lot of other demands on my time and with my two old cars I am looking to use modern items to shave just a bit of time off my ongoing maintenance requirements.

and again...no feedback on the problems you encountered fitting the distributor and how you overcome these problems you were so exasperated about with your opening thread..inquiring minds want to know and in reality those who helped with advice deserve a bit of feedback also...

What Plymouthy is trying to say is what did you do to fix the misfit problems? Help us all learn from your issues.

Hi Plymouthy/Don.

 

Sorry I was not clear on this aspect (but did elude to it on post #7). On the HEI dizzy I took off the collar at the top of the shaft (the one with the spring pin through it) and chamfered the bottom edge and then shaved 1/2 a mm off the diameter. Reassembled it.

 

Then with wiggling and jiggling and pointing the vacuum can downward it slides in and engages the tang into the oil pump. There is enough swing in this position to set timing and all is good.

thanks for the clarification...

So, you modified the modified product for a better fit into it,s adopted home. The home was fine as it was designed.
