Is it the 138 hp factory version (rated 213 NHRA), or the 140 (NHRA rated 223)?

The car shipping weight is 3,178 pounds. The 307/138-213 is a natural SS/MA, that can also run LA and NA. The 307/140-223 runs the same three classes.

Top weight break of the class (13.00 pounds for L, 14.00 for M and 15.00 for N), multiplied by the NHRA rating of the motor, plus 170 pounds for driver, equals minimum weight, with driver, the car must cross the scales at. So:

SS/NA, 223 x 15 + 170 = 3,515 pounds at the end of the run, with driver.

Hope this helps.
