That's it on the RPM? That's stock territory. I figured RPM potential to be higher, like 7+. Shows how much I know. Guess it depends on the combo but that seems low for a 13:1 mill.
Got as much torque as Horsepower. Don't need RPM to go fast. This motor was built to live. We set the piston out of the hole 18 thousands to get Compression. The heads are the key to the combination. big valve and lots of flow at 6000 rpm. Also the right center line cam helps to make the torque. It 60's at 1.47 -1.48 all day long. Needs lot of tire but not to tall. Leave the line at 4200.
