LA 360 or Magnum 5.9

Only complaint I hear between 318 and 360 is torque. Need more torque for heavier car

Ya basically but it more do gearing. Say a 350hp 360 optimal gear for the 1/4 is 3.73 and a 350hp 318 say would be 4.10. And you were gonna run 3.55. The 360 would be slighty under geared but the 318 would majorly under geared.
