I am using Engine Analyzer 3.0 program to try and select the camshaft for my stroked 390. Part of the data input is the primary size and collector data. I haven't taken delivery on these parts yet so can't go to the shop and measure it.

Does anyone have this info that I can plug into the program:
Primary length
Collector length
Overall exhaust length (from primary end to exhaust opening.

Thanks

Paul
