I have a friend who has one. It has a 440 in it. It was a total SLUG when I first met him. I convinced him several years ago to let me have it for a week. 440 was mild, but not stock. Hp manifolds, aluminum intake Holley 750, but wouldn't get out of its own way. I pulled the front off, put a degree wheel on it, advanced the cam timing, got it back running and recurved the distributor. got the carburetor in tune. I just bet I added at least 75 LB FT. Now it will melt the back tires with very little effort. It's a damned nice car too. T-tops and all.
