Well i mean, we just got a MSD 6AL box off of ebay for $150 and stuck on the Camaro, had no problems or anything out of it, its fine and we got the billet dizzy and had no problems from that either. But thats on a 396 chevy engine, so....i dont really know if the quality is any different for the Ford dizzy's VS. Chevys....I was just wondering if one put out more spark than the other.
