Hello. I am new to this board, but have been visitng for a while to see what go's on here. All I can say is this is great.<br />I have a 82 glasscraft with a 228 Mercruiser (305) chevy. It has points ignition and I want to Put a HEI system on it and was wondering if a dis out of a car engine will work. The one in the boat right now will wiggle or move if you push it to one side or the other. The timeing is iratic when you use the timing light. What are your thoughts, and thanks for the help.
