ok so i am a newbie here and have a question of what is this boat worth. i currently am a marine mechanic here on long island and have a boat in my yard for over 12 years. it's is a 18' challenger thinking it to be around a '74 because it looks just like the one that is listed on this forums classifieds. i had it running 10 years ago but it kept burning out coils so we stopped working on cause the customer did not want to put anymore cash into it. it has a 454bbc with a B&M blower running 2 what i believe to be 600 cfm holleys. boat has basset headers, and a berkley jet just not sure what model jet though. i can find out. boats motor is currently now in pieces because the customer did not want to reshrinkwrap the boat and water got into it. i have everything to put it back together engine condition is not to bad just a quick rebuild and it should be fine. interior has been chewed up a bit by squirrels or a racoon but repairable and the hull was repainted about 12-15 years ago and looks pretty good. how good are these hulls and what kind of speed should i see with about 600 horsepower. gonna offer the guy $500 for the boat, trailer, and everything else. any help or history on these boats would be helpful. thanks, Marty
