thank you doublevision
It is a 350 bored over .030 and has 882 heads with 282 crane cam. I know get rid of that cam...What should i go to? I have a turbo 350 trans with a 3.73 gears and the gears are non-negotable. 600 cfm edelbrock carb dual flowmasters (not sure what series) I have the cheapo spark plugs on it right now but only until i get it running. It has never been cranked since it was rebuilt. I just put oil in it for the first time ever. Would anyone care to venture a guess as to what i might get mileage wise right now no mods?
