300 HP 360 Magnum Crate Motor Upgrades

Hot Rod has a great article for 412 HP under "Junkyard Jewel" for this motor.
Good to know deals are still out there on these original motors. Prob. Very very few these days. I got a barn find new 380 HP 2yrs ago now in my 73 Duster.

Do the upgrade if you can as at the car will SCREAM. Last summer a guy was selling a 380 hp at Carlisle for 2k.
