with that protronics kit it comes with a .30 feeler gauge and tells you that should be your air gap and has a screw Just Like Old points so you can sit that Gap.... so I figured I would check the dwell.. all the numbers I found on the car and the motor and all the searching iv done online is saying it's a 225 I'll double check numbers. But that number search should be right right or is there another way to tell?
