Genuine 5.0ltr sle 11/81 model, engine rebuilt with solid crow cam, roller rockers crow pushrods and valves, retainers and springs. Flattop pistons 9.8:1 compression, edelbrock intake manifold match ported to heads and a 650 double pumper holley.. Aparently it came out as a "country pack" so had 10 bolt disc salisbury and towing suspension so sits a little higher than stock but ill be changing that soon. Not a single mark in the interior. Im the third owner in its life, bought it off my dad 2 yrs ago an he owned it for 10 yrs previously.. Still had all log books and original plates that were on it when it was sold new..
