72 turn key 340 complete carb to oil pan

You should start a new thread. Mention that you have a stock 72 340 that you would like to outperform a stock 70 340.

Mention the rest of your drivetrain, gearing, if you want headers or not. What fuel you want to run. Do you want to stay with the intake and carb you have now……

Shouldn't be a very big deal getting you where you want to be.
