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

Don't have a solution for your problem but I'll have to admit it is the first time i have heard of a six with straight pipes not having a "wrap".

rap rap, not wrap wrap?

From the experts on producing such noises.

All I know is that my 261, with many carburetor setups and two different dual pipe/exhaust setups, made/makes too much noise.

Enough that a police officer pulled me over and told me that he had called me in because my rapping made him fearful that I would try to run him (I asked him if he would please write that on the ticket/summons).

Gleaned from the link above: if you are using original diameter pipes, you should expect reduced "rapping".
The 216 engine might also have only minimal rapping potential?

Have you tried playing different music for it? Maybe it's just not in the mood to rap to your choice of tunes!

Joking aside, Jerry. If you wanted a 216 to "rap", would smaller diameter exhaust system pipes help?
High-pitched raps?

Smaller pipes will create higher velocity in the exhaust system, but the placement of the muffler(s) is the critical factor. Low-restriction mufflers close to the engine and a long tailpipe will allow for more resonance. I've got a cure for loud pipes- - - -it involves a good bench rest and an accurate rifle!

Amen, Jerry

I have always thought that loud pipes are for people with certain character/physical traits that are inappropriate to specify in any forum here.

I hope you do not mind me including motorcycles.

My Honda Gold Wing 1100 is whisper-quiet, and it's going to stay that way. "Short man syndrome" is a real thing, according to a few public school psychologists I've worked with!
