I read about it here on moparts but don't recall what I read.

look at speedmaster.com for cheap billet pro-comp dist also.

billet SB or BB dist cheap 59$-79$



matter of fact, they have the same elect fuel pump that I buy at my local speed shop for 120$ for 40$ free shipping too.

I have started buying from speed master for most of my needs even though the speed shop has the EXACT same thing on the shelf. get 3x as many parts/free shipping for same $ with speed masters.

pays to shop around sometimes
