It sounds like your Dist. might be off a tooth. Even though you are moving the Dist. If it is off you will have to remove the Dist. And retard it one tooth. Thhis sounds like it could beyour problem althogh you didn't say where it was backfiring from Carbs or Exhaust. Put A timing light on the car and see where you are at as far as timing goes good luck.

Check your vaccum lines too. Make sure they're all healthy and tight. Lee Z

280 radiator

Nope, I tried putting a 280 radiator into my 260, just wouldn't go. If I remember correctly, it was to tall and to narrow? The narrow problem could be fixed by drilling different spaced holes, but it was so tall that even if it sat on the chasis underneath, I still couldn't close the hood. To fit it, I would of had to of chopped the core, but for all the modifications required, you might as modify any radiator you like, not just a 280. I eventualy just got my origional radiatior recored and the header and footer tanks renovated.

You would think it should of fit, wouldn't ya? But then life sucks.
