right this is why racing cars are grouped according to engine cid, weight. could you imagine the 1970 trams am cars with big heavy 440's 460's 454's in them trying to brake and turn, or in drag racing a 4,000 lbs charger with a stock 440 racing a stock 428scj 68 mustang, bottom line the 440 should win if the hp is the same, due to more torque but then again if both were in a 3,400 lbs duster i would think the lighter 360 with the lighter and less hp eating 904 would make for a close race, oh and i forgot the hi torque of the 440 might kill the 8 3/4 so it might need a heavy dana where the 360 will not kill the 8 3/4.
