True HEI distributor conversion thoughts

I have the big cap GM HEI version in the 351M in my 75 F250. Been in it for about three years now. Hasn't missed a beat. Comes with about 20* mechanical advance. I limited mine to 15* by drilling a small hole in the breaker plate and installing a screw to stop the advance plate. I have it set on 20* initial and 35* total. So far it has run very well. I have zero complaints.

All these type are the same, whether they are Skip White, ProComp.......whatever. Although I have read about some issues, I drive mine everyday and have zero complaints.
