to be honest: i don't remember any speeds for the ranchero.
i think we ran 168 with the 260... maybe...
we ran a 221 small block in f/prod and the 260 in e/prod and probably also ran it in gas coupe at el mirage.
that was in the days before the cubic inch min/max were changed.
the 221 eventually became a 180 incher after the change.
the 260 is the same engine that found its way into the redhead.
both of those engines came from ak miller and jack lufkin.
i think ak ran the 221 and jack ran the 260.
but, jack did hold every sports racing record at one time. so, he may have raced the 221 in f/sr. that was in the days of f being the smallest engine category.
we got a lot of experimental ford high performance products from ak; some worked and others didn't:
my '70 ranchero (351 cleveland) had an experimental ford cam and other non-stock goodies.
my '64 ranchero (the yellow one that frank oddo probably still owns) had a 302 from a detomaso mangusta that had been jazzed up with a bunch of experimental ford items.
both of those engines and associated parts came courtesy of jack lufkin and ak miller.
i don't know what it was about those small blocks that we raced. but, we always got comments about the way they sounded; we were always accused of running more inches than we did. of course, post-record run impounds showed the proof.
maybe it was just 9000 rpm in the lights with stock cranks and rods.
