With all the money and time you'd put into it to get the HP up you'd be better off buying another vehicle to drive to Vegas, or just fly there.

Don't discount what a good exhaust system can do for you. I had one on my old doggy Land Cruiser and after the new one it was like I had an extra gear. I could run over Floyd Hill at the speed limit which I could never do before with the stock setup.

These are what I'm using.
Without re-gearing, or better yet doing a driveline swap, IMO you are at or nearly at max performance with your current rig. Doohickeys, gadgets, gizmos and other assorted bolt-ons never meet their advertised performance gains, particularly on CPU controlled engines. Chips and programmers help, but the old saying "no replacement for displacement" is true, and trying to prove it false often leads to many expensive mods that never quite add up.
I had a 1979 chevy luv 4x4 back in the day. They were isuzus. I put slighly larger tires on it and to gain back power I put in a webber carb, headers, and a racing distributer, and flow thru exhaust. Regearing would have been simpler. All those upgrades were a waste of time and money imo.

IMHO - The bottom line is it costs money to go fast. Exhaust/intake/cam may offer moderate improvements but can get pretty expensive (especially if you have a shop do the work). If you are already seeing 3,500 RPM on the highway then gearing is not going to help you.
If all you really need is more power on the occasional steep mountain pass, you might consider this;
P.S. - Stop going to Vegas and you may discover more money in your budget.

And I'd prefer to have more acceleration. What I'm gonna do is get the exhaust done first. Then if I'm not happy I'm gonna do the camshaft kit.
IF you consider re-gearing, I think the Isuzu models came with a D44 rear end with a removable 3rd member. That means you can do some of the work to minimize the cost. But since it is an Isuzu, parts may be harder to find, and gearing may cost more due to the difficult to find parts. I agree that gears would help, and keeping it at 65mph on the highway.
Tom is probably not far off though in order to get the kind of punch you're probably looking for. My Explorer is 160hp and will end up being just a wheeler. I have a sports car for when I need to crank some turns and get pinned in the seat. That might be a viable option for you, especially to go to Vegas, just get a faster car and enjoy the best of both worlds. For the amount of money it would take to get your Rodeo buzzing, you could have a nice quick little car that won't kill you at the pump.
You ask for help but you appear to reject all suggestions
