Hi Guys, wondering if you can help. I've got a Y Block in my F100. Its not the original engine, it was fitted some point later in its life. I was told its a 272cu, but if im right looking at the casting it number its actually a 292cu. Am i right?  It appears to be B9AE



 I have an issue with it where it hesitates now and then and back fires. Feels like the advance isnt working correctly, also the points need changing. I did order some which i thought were correct but they werent.

I've decided to go with an electronic distrubutor, but i need to know which to order. Im unsure if my dizzy is Load-o-Matic or not.  Can you tell from this picture?



Any help is appreciated.


Kind Regards,

Jay
