Diesel engines


Does anyone know which engine is superior or if one performs better than the other?
Cat C7 350 horse or Cummins ISC 330 horse?

Also, I'm getting different opinions on a 4 bag air chassis compared to 8 bag air chassis. Any thoughts on this subject?

Thanks for your help!

I just put a long trip on a 350 HP Cummins ISC, and I was quite happy with it. It slowed down going up hills, but showed no sign of strain.

Horsepower is the headline but torque pulls you up those hills. I am a very happy Cummins fan but would always suggest the engine with the most torque. That is where the rubber hits the road.
