Well----- The crank on this engine was ruined when I bought it so I swapped in a 120 crank.That's what I had! The engine sat for about 4-5 years before I had this use for it.
It was originally a Prestolite ignition which I converted to distributor Motorola ignition--because I had one.
Because the crank stroke is 2.80 versus 2.875 with the 125, and because the ports are higher in the cylinder wall, compression is down to 120 PSI. I really was wondering how this engine would perform. It did remarkably well, driving the 1971 Glastron V153 to 47 MPH.
Strangely enough, I must have left the bottom carb bowl bolt loose because the bottom bowl fell off completely. Oh, Man! Gas was blowing all over under the hood! The engine was doing about 25-30 on two cylinders before I realized what happened and replaced the bowl
You can see the video of it running well at http://youtu.be/fvg_ICcKWis Chrysler 125 with a 120 crankshaft. The second half of the video is boring as I was in shallow water but I do not yet know how to edit videos.
The guy that I wave to is in a Sunbird onto which I mounted a rebuilt Chrysler 75 about 5 years ago. I was surprised to see the engine and the guy who just bought it is very happy with it.
