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
