Converting 318 to Dual Exhaust

My winter motor was a LC teener (circa 1973). I ran the same TTIs and 3 inch H-piped pipes with the same Dynomaxers(circa 1999), that I run on the summer 360 motor.
Very pleasant tone.Loud but not overly so (subjective, I know) Lots of torque. I ran it with every gear from 2.76 to 3.55. I actually liked the 2.76s. The TQ moan was never ending! I ran the teener with the low first/loc-up 904, and about a 2400 TC.
I eventually sold that engine to my son,cuz he liked it so much. Many years later, I bought it back.Now it sits languishing under the hood of a worn out 84 D100.(the body,not the engine)
All the best to you
