Ol' Blue's magnum swap

Funny thing.... I bought the same distributor and wires on my 87 dakota that I put a 5.9 magnum in...
If you dont mind me asking, what is your opinion on the HEI distributor?
Mine came with a bad vacuum advance. Got it replaced. No big deal.
But it seems that the mechanical advance is too slow, and it advances too much.
Im going to get a recurve kit and play with it.
