You need to let us know which rear end gears you have. My 72 fastback with a 351c and basicly a full performer set up with a 2.79 rear end pulled a 14.6. Also, which tranny do you have.

If you cannot find an obvious rust hole or seam separation might be the weather strip is not sealing due to being old and taken a set which precludes contact with the drip edge. The way to check is to close the deck lid on a strip of paper and see if there is resistance when you try to pull it out. If no resistance there is probably a gap between the weather strip and the drip edge. New weather strip is readily available but need to use the right size and correct adhesive. Another possibility is a rust hole under the rear window gasket. Suspect you already put an expendable bud in the trunk to watch for leaks while you hosed it down.

My car's set up almost identical to Johns, 'cept I have a little taller gear, but not much, a 3.25.... I figure I'd run low 14's in the 1/4 on a good day w/ a good launch, and I would begin to guess at my HP, 177 net from the factory, I'd figure about 240, 250, but its just a guess.
