I've been noticing with my '60 ragtop that it doesn't have as much zip as my
'66 'vert. They both have new 1600s, with the difference being that the '66 has
a single port with a 30/31 Pict and sinlge vac diz and the '60 has a dual port
with a 34 PICT and the push/pull diz. I think they are both timed correctly,
5ATDC for the '60, though who knows if the carb is adjusted proper. I used the
technique described by Jan and the car idles fine and travels well on the
freeway. THe problem is acceleration. WHen I "punch" the pedal there is a very
gradual increase in speed. I can't say hesitation, just a very unresponsive
throttle especially at speed. On long grades it has a more difficult time
holding speed compared to my '66. The 60 is supposed to have a "freeway flyer"
trans in it, at least according to the PO. Could the taller gearing account for
the difference in response, especially in third and fourth or could it be a
Thanks for any ideas.
