My brother is in the market for a new distributor for his 460 (Edelbrock heads, 850 demon carb, 280* adv. cam) and found a guy selling "Pro Comp" brand ignition setup (distributor, '6AL' box, coil) for cheap and was wondering about the quality. He was also considering the DUI setup like advertized here. Any input? I've an MSD Pro Billet on my 289 and it's run great... and my Mallory Unilite in the Bronco has been no problems as well but I wouldn't use it in a high-performance app like his. He's had a Holley Annihilator distributor and also a Mallory electronic one and had problems with both, so looking for an alternative to those.
