Banshee, the noise is constant and located on one of the rear two cylinders on the passenger side. Pulling the plug wire is inconclusive as the engine is pretty loud and is probably a 450+hp engine. At idle you can hear it but you have to rev it a little to keep it running on 7 cylinders. I may have a timing issue as well, but the noise was there before i fiddled with the timing. At present, the trans is out of the car and i have test run it that way. Pulling it wont really be a big deal, as i want to clean it up while it is out.

My concern is that i will end up paying for a rebuild when it may not be needed. The PO said it only had 1500 miles on it since the build (done by him and a buddy in his backyard shop).
