Just after I put the 3.54's in my '59 I drove it home, got about 17.5 MPG,
including a little stop and go driving to work. RPMs about 2600-2700
Before the swap I got about 14.5-15 mpg at 3000rpms.
But the last few trips to my Dads place, I was averaging about 14.5 again,
still turning about 2600-2700 rpms, had me thinking I was running too rich.
Also been noticing a little "popping" or "chuggling" through the carb, but I
din't think about it much, so I set the timng back a few degrees, the popping
and chuggling went away, tightened down the distributor and revved the motor
up a few time.
Was just getting ready to close the hood but decided to rev it once more,
and noticed the distributor sitting there solid as a rock, no movement at
all, hmmn, looks like the vacuum advance diaphram musta taken a dump.
This would explain the loss of milage.
Just wanted to relay this for ya'll to take a look at your inlines and make
sure you're getting advance. Now I'm wondering if the wieghts may be frozen
in it too?
Guess it's time to put the HEI in I bought off the list last year.
Also, tomorrow morning I'm signing an offer letter on the place next door to
my Dads, it has two homes on it and 3 acres, I'm going to let my Sister and
Brother-inlaw lease to own 1/2 and rent the other side out, for my troubles
and down payment to get it started, I'm taking over the barn. It used to be
a pig barn, has a cement slab floor, concrete foundation block side up about
6 feet and they've been extended another 4 feet with wood, on top of that is
a tin roof. The "barn" (notice the " "'s) is 20 x 40.
It won't be a shop so to speak, but it will be my ideal place to store the
numerous vehicles iIve passed on over the years. I can now go back to
looking out in fields and behind barns for old cars and trucks to buy, I feel
like a kid again:)
