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.
