Good quality fuel pump ? or is there any Diffe

Guys over on slantsix.org get one from a big block(440 HP& Hemi) and drive out the rollpin that holds the arm in place and use the arm off the old slant pump. That way you can use the rebuildable Carter and index the fuel lines where you want.Mancini has them,they ain't cheap about a $100 bucks. Just a thought.
