you will need 360 motor mounts for the old LA style blocks to go in where a 273 was
273,318,340 are a different mount than a LA360
the mag engen will have the old LA engine mount bosses and some engine mount boss in the middle of the block for the magnum "ram" trucks mounts
B&M flex plate for 360 magnum engine will use the 273,318,340, torque converters which are nutural balance
the old 273 dist will fit in the mag engine
the old LA style timming cover and v belts all bolt on
the cam is a roller cam with a short nose and can not run a fuel pump
there are adaptors for this to run the ecentric and stock fuel pump
you will need a 360 car oil pan if you put it in a car
its a great swap with a carb/intake,elect dist,headers into an older ride
you can run the newer mini starter also which is a good upgrade for it as well
