It a 383 with the 750 slayer quick fuel carburetor and a talker cam which gives it 10 to 1 so I’m using high-octane with plugs in the middle range. Is there anything else that I should put up here and again I sure appreciate everyone’s help this is been quite a deal for me I’m not some certified auto mechanic.

Sorry I meant torquer cam So what seems it comes back to the carburetor. And it ran OK but it was fouling plugs. I’ll check the floats and I got a size smaller jet and a vacuum gauge I’ll see what happens
