I currently have a summit base with MSD cap & rotor kit. Works excellent right now :knock on wood:
When I first started my heads & cam combo, I purchased a new complete Summit kit, and it must have been faulty from the start because I had a nasty miss with anything over 3k. When I discovered the problem, I simply called up Summit and returned the faulty one and they had a new one to me in a day or two. They were A+ on service and getting a replacement to me.
