Yep - that was her. The only mod I made was to replace the stock distributor/coil with a Mallory dual-point so that little engine would happily hit its 7200 RPM red-line with joy. I had a (numerically) low rear-end so your first shift was 62-64 MPH at 7200 RPM. What a joyous sound. (those bias-ply tires made everything just a bit scary.)
