Nitrous Pro Modified?
Sonny's we had didn't make 2000 na.Pretty close but not quite.If you're talking no power adders and automobile racing I'd think one of those big inch Sonny's or Musi PM engines would get the nod. They're what - 2100,2200hp?
I don't know. Some of the Kohler's will give it a run for their money!I would say the Briggs vanguard twin cyl pretty stout.
