How much does a 1969 Mustang 302 weigh?

Approximately 3,210 lbs.

Here's a table I posted a few months back. It shows the weights of many models, including some small block Mustangs. Be sure to read the caveat at the end regarding curb weight vs. as-tested weight.

The columns are like this:

17.4 @ 84--'67 Mustang----4spd--289/225--2980 138/172--03/67 RT To calculate the rwhp (or fwhp or all-whp) I used the formula hp = weight * (speed / 234)^3. Fwhp = rwhp/0.80.

The weight was problematic. Some of the weights are "as-tested," while some are "curb weight." As-tested would equal curb weight plus driver plus gas @ 7 lbs./gallon. The lower the weight, the lower the calculated hp. So if a weight number seems bogus to you, just add 250 lbs. and do the calc yourself, fwhp = (weight * (speed/234)^3)/0.80.
