might have found a 440 for my 62 dart, It was built for a ski boat and has about 25 hours on it supposedly. It was for a propeller boat, not a pump. the only thing i can tell u for sure is it has ISKY adjustable rockers , and an edelbock Performer RPM manifold. what is inside i can only guess. Heres a few things i was wondering about, 1) How are ski boat motors usually cammed? would they be similar to a street caM OR ????? 2) hOW ABOUT ROTATION, i hear some boat motors are made to run backwards.??? 3) how about compression, would it be high compression?? the price is right, and the guy seems like a straight shooter, but....... neal zimmerman, eugene oregon
