fastest in my school was my buddy craigs 65 GTO.this was back in 1976,with 391 rears and plenty of abuse he could get a little daylight under the front tires(at least till the motor went boom).high school back then was wild...made fast times at ridgemont high look like a movie about a strict catholic school.i had a 67 mustang with a 289,it was decent for a small block.still got around 10 miles per gallon which sucked when gas went up to 50 cents a gallon.
