what needs to be changed in a 72 340 to be like a 70 340?

One of the reason's I think my change was so huge is because all my power is in the area where the manifolds simply don't flow. They are not doing the job from 5,500-8,000.


The other changes were…..

Electric fan and electric water pump drive to stock belt driven fan and standard water pump.

Slicks to stock tires.

SS springs to XHD springs.
