Did some small blocks come without AIR injection and a smog pump? If so, they would take a shorter belt I would think.

Rick, thanks for the info!

You're right Paul.
I gave you the wrong belt numbers.
I have those two used belts hanging here on a wall,and forgot they were taken off of NON A.I.R/solid lifter equipped smallblocks.

These are the correct belts for the 1970-74 Z/28 LT-1.
*Fan/Alt. w/A.I.R #3883248,later superseded by #9433746.Both measure 3/8 X 47".
*Power Steering #3986192,later superseded by #9433723.Both measure 3/8 X 35".
