That was when i junked it and bought the '73 Chevy step van. It had

The 292 was a great egine - lots of torque.
Just knew the 283 was "yesterday's news" by 1968

Only "yesterday's news" because GM kept increasing the bore until they
would only last as long as the rest of the car.

Actually the last of the "real" sbc 250s outlasted the average 283 by
a factor of better than 2. Virtually never got a valve job, ring job,
or bearing replacement - all of which were common in 1963 on the 283
before 80,000 miles.
