With a smaller cam, 1st gear isn't usable, well maybe for a parking lot. Even with the 292H, I take off in 2nd gear most times.
the 292H is back to making torque at 3000 rpms which would be around 20mph in first gear (4.11 gear, 2.75 first gear, 26 inch tire).
He has an M-21 close ratio Muncie with 2.20 first gear. Assuming a 26 inch tire he would be turning 6400 RPM @ 55 MPH in 1st, that better be one long parking lot!
