Motor is a 383, less then 2000 miles on it.
Was going to start taking the front apart as the previous owner installed loud timing gear set.
Thought I would check the timing first and see where its at.
At idle I cannot get close to a steady reading. The balancer, well everything actually is new, and the line on the balancer is clear. But it jumps so bad I can't get a good read. It looks as high as 30* ish but really I don't know. At 3000rpm it shows 40* and I know this is way too much. With the vacuum advance hooked up it was as high as 50* at idle.
What could cause the jumping at idle? It does have an HEI with an external blaster2 coil and a 6a box. I have read about dial back lights and msd box problems before, but this is the same light I used on several of my cars and dads car with the same msd components and never had an issue. Could this be an issue with the gear drive?
Idle speed is at 1000, could it be the advance coming in causing this?
Problem is when I try and lower idle speed it will stall in gear. Idle set at 900-1000, in gear its at 500rpm.
