One additional note on Pro Comp.

They are the gloriously tacky company that copies just about every other USA made manufacturers parts. Not quality wise, but in exact looks. Pro Comp makes cheap Chinese made distributors and Multiple Spark ignition boxes. MSD was successful recently in getting a court order to make Pro Comp stop manufacturing their blatant rip off of the 6AL box. Pro Comp also makes an exact look alike knock off of Flex-A-Lite's 5.0 electric fan. They damage companies like MSD, Edelbrock, and Flex-A-Lite by selling an inferior product that looks identical to products of companies that actually invested research and development costs into a good product, not just in stolen sales but when Pro Comp products go bad, the consumer who doesn't notice the brand difference will think "all the red ignition boxes" are junk. Think I'm wrong? Ask Flex-A-Lite how many tech calls they get from customers complaining about their Flex-A-Lite 185 fans that are defective only to have to waste the Flex-A-Lite tech's time when the Flex-A-Lite tech realizes and then has to explain that what the customer bought was a Pro Comp ripoff.
