Looking for some advise on my trouble with my 1951 216 engine . For some reason I’m not getting much or most the time no wrapping noise come out my exhaust . I had manifold split. Intake was porcelined for look and exhaust manifold was jet coated. I’m am wondering where to begin with my trouble shooting . What would be most likely my issue with no wrap coming out of engine . I have timed engine rebuilt carb made sure my vacume advance moved on acceleration . And exhaust manifold seems not to be leaking air I also removed my glass pack and currently running strait pipes still very little wrap .any advice or past experiences would be appreciated
