360’s have very low compression if built as stock; static is something like 8:1. The pistons are way down in the hole and the stock cam has minimum lift and little duration. They were designed for trucks to pull hard at low rpms and get reasonable fuel economy at speed... It would certainly be a disappointment in a car.
If you change the cam to a more aggressive pattern it may get worse because your dynamic compression will fall off even more.
