347 vs 370 differance
347 vs 370 differance Assuming each motor is in identical cars with the same D1 procharger and same 3.4" blower pulley with same heads, exhaust, intake ect ect what would the likely power difference be between the two? I know the 370 would be more efficient but the 347 would weigh more in my case due to the aluminum vs iron block. Just trying to see if the extra power of the 370 iron blocked motor would offset the weight savings of reusing my aluminum block.

The 370 will offer you more torque. For the most part your blower will dictate maximum power available, not engine size.
Either could be had with aluminium block.
