The motor pulled 400HP on the engine dyno. Are you saying with a different cam I could pull 450 at the rear wheels? Thats a hell of change off a cam swap. I've been told I could add about 100HP from a cam swap, but was sceptical. I've listed my current setup at the top of the post, what cam do you recommend. Again, my goal was a streetable combo I can cruise 8 hours with. More HP would be great, and maybe I'll make the swap before I leave the country, just for fun. Recommendations? Thanks.
