Cam choice?..

Oh ... I didnt realize that part.

You could just punch a hole in the muffler ! Lol
Back in 79/80 My 70 Chargers mufflers were going south and people would always compliment the awesome sound of it .
“ What cam are you running ? “.....lol
the problem is I'll be selling it to someone like you or me who will be older and know the difference between the hole in the muffler and something that sounds healthy with a quiet Muffler...
