Problems with 360 LA distributor

Just looked at those distributors you posted. No curve info and they fit a wide spread of motors and years. Hit or miss if it would work well. That's one of the problems with those. Usually they are made well. What is the shipping on one of those from here to there? I get the local rate.
I know what you mean, its like when a carb is sold as 'jetted' to your engine. How do they now what cam, CR header carb etc you have.

I think mine is a stock 360 LA engine date stamped 1980. As in stock cam and heads. I'll get a photo of the dizzy ID tag
