They're aren't a lot of hop-ups that you can do to a Nitro Hammer besides what I've listed above. You can try upping the nitro percentage to around 40-45% for a little more speed. If you wanted to get a little more radical, a suface drive setup could be installed to help unload the prop.

Yamblaster, where are you at in Michigan? Next June, we are having a Fun Run probably again here in Kalamazoo or maybe in the Grand Rapids area. Anyone with a boat is welcome to show up and "run wutcha brung". There is a Hobby Shop nearby in case someone doesn't have what somebody might need in case something breaks or my house with a basement full of stuff isn't too far away either. There should be a lot of "small block" boats there with my 4 plus at least 6 others that I know of.
