I got one of there "pro-billet" big block distys (for my 402BBC) ... If I had to do it again I would get the one with the vac advance to help with fuel efficiency and heat. I did have a problem with magnetic pickup going south after just a couple months and very few miles. They sent a replacement pickup and haven't had any trouble since last spring (although I did get a spare pickup just in case it happens again)...

Two cents,
