#1981, "RE: 4g63 vs. 67 mustang" In response to In response to 1
is the mustang a 3 speed?
and, does it have just one 2 barrel carbeurator?
if so then it shouldn't be that fast, from what I have been able to find out (and I'm not sure how accurate the info is) the low end V8 mustang in '67 had 200 or 225 gross HP (which would be about 20-30 less net, which is how HP is measured today)
my dad always said the lowest level V8 option with a 2 barrel on the old cars were slow (well, relatiely speaking)
