I think Sean would agree with me that the issue with the 305 TPI motor is where the torque starts to ramp up
and that the intake manifold/heads basically suffocate the motor at 4500 RPM. The LS motors start making torque
at a lower RPM and then can rev another 1500 RPM over the TPI which completely changes your shift points
particularly during cornering.

Speedo is not a huge deal. But the tach, hope that's on your list to add soon.
