It is a 360 and 727. I don’t know much else. Rpm keeps going up as I advance past 30 and higher…. I think I have it set at 18 btdc but I’ve played around with it a lot trying to smooth it out. I’ll be honest I didn’t know there were different flywheel torque converters that can be used with this combo so I’ll have to do some research if you guys think that’s a contributing factor. Is it possible to see what flex plate and torque converter is there without pulling the transmission? I thought all 360’s were externally balanced. Sorry, I’ve never been too far inside an engine so learning.
