Ok, if it already has a healthy sounding cam in it now and it ran 7's in the Duster what do you think you can accomplish? Sounds like it must be built pretty well now. If you want it to sound like a top fuel dragster go ahead but most likely, like others have already pointed out, you'll just slow it down and waste money doing so. If your plans are to build a stroker why not save the money and use it to make the stroker a killer engine?
