How cool, an old "J" converter. We used to run them in the stockers and super stockers as they were nearly bullet proof. When you look down the snout, is it clean inside (no rust or anything on the metal parts)? Have you poured any old fluid out to see what it looks like? If its a steet car, what the hay.. But be aware, the J converters are alot of verter to run on the street. We have never run one other than down the 1/4 mile. I have heard they build heat quickly and not the good choice for a "driver".
