I believe it was from a 250,or 292 engine(I have a 235) Is this correct? Has anyone done this? | | | | | Joined: Feb 2001 Posts: 1,094 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 1,094 | It doesn't just fit. Put a pertronics ignition in, or look at Langdon's stovebolt engine co., He has one already modified and ready to drop in.

Talked to Petronix as they thought I could have purchased one of three available for our trucks a couple of years ago. They thought if I had an old unit, it could be indexed wrong.
I have the correct unit for my 228 GMC, so I am still working on getting my advance back.
Any advice? | | | | | Joined: Jun 2012 Posts: 142 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 142 | I am not the best mechanic,but I did not think it would just go in.

Any advice? Did you dig deeper into the distributor to determine the condition of the mechanical advance mechanism? There are springs, advance weights, and the pins which the weights ride on. Lots of places for wear to occur.
