I had a 68 Dart GTS back in the mid 70's with a 360 from a 72 in it.
I had the engine rebuilt and the Guy who did it says he put in a "purple camshaft with the Hemi grind??? " into the car. The car had great power but one heck of a rought idle. You could count it fire it seemd like yet I drove it every day. Is this possibly same cam?
I also had a very thick soft cover manual I bought from chrysler dealer back then. It contained every setup, chasis, engine , rearend ect and what times to expect the car to run. DIRECT CONNECTION MANUAL??? Anyone remember that one.
