Take it to a track and find out what the cars likes as far a shift RPM, try 5500, then 600 and 6500 RPM scope
look at the 60 Ft. times and 330, 660,1000 Ft. and finally, the 1/4-mile times.
My last pump gas stroker motor made peak torque at 4500 RPM and peak HP at 5500 RPM on several different engine dynos but the combination like to be shifted above 7000 RPM at the track for best ET and MPH shruggy scope
Theory is one thing when it comes to our hobby and real world results can and sometimes don't follow theory, the only way to learn what works the best on your parts is to test, test and then test some more up scope
