Bill, in the finest traditions of Garbage-in-Garbage-out, we don't
really know , yet, what the actual road HP, or vehicle weight may have
been, on the car that ran at Daytona.
We might be able to confirm the as-raced weight, from the NHRA
archivist, but unless we can score the factory's dynamometer read outs
(which almost certainly were recorded, before shipping the car off to
Daytona) it will be difficult to project various perfect-world/traction/
weather condition quarter mile times.
But, until then, various combinations of variables can be plugged into
the formula.

This or any other reputable calculator should not be so lightly
dismissed. These simple programs obviously do not take all factors
into consideration. But, they do provide an ideal situation based
on ideal conditions. Yup, leaving a one legged 50' long tire stripe
will throw the calculations off. But this discussion has turned
into "What was possible", since there are no extant
records. Driver skill will approach the ideal, but I don't believe
it will surpass it.
I have fooled with the same GTX for over 28 years. Tuning and
practice all make a difference, but it is an incremental difference of
tenths or hundredths of seconds. That will win or lose the race,
but most similar cars driven in a similar manner will have similar
terminal speeds, since that is a function of HP. The actual E.T.
will vary, but only by a little assuming equal driving skills.
My GTX has a best E.T. of 12.55 at some speed around 105, can't remember
and don't know where the time slips are since I haven't raced in a couple
of years. This was with 30"/10.5" slicks and open
headers. These calculators predicted about a 12.49 for my
car. I think that is pretty close given all possible
variables.
They provide just an estimate, but if the estimate wasn't at least in the
ball park, some really professional outfits wouldn't use them.
There are other calculators that cost some dough that can take virtually
any variable known into account, but these free ones are just put forth
as an estimate for what is supposed to be an enlightening and possibly
entertaining discussion.
Here are some others for a comparison check.

Wow if that really
works I guess there is no need to spend all of this time at a drag strip.
Tire pressure,aerodynamics, driver skills,traction,tuning,atmospheric
conditions all really never made as much of a difference as we all
thought! Give me a break! And try more likely 3800 pounds!
