Thanks for the info Captkaos! It looks interesting! Do you have any experience with it?

They aren't cheap, but have you considered a Gear Vendors overdrive?  This would allow you to keep the SM465 and Tcase and just bolt it to the back of the transfercase.

Is there an Automatic Transmission that would be a better fit with less modifications. Also, I will have to worry about my exhaust system. I just need better highway driving than what the SM465 provides.

When you say the tunnel cover would have to be modified for length, are you saying I would have to cut a new hole (move the hole for the shifter or actually the cover itself would need to be lengthened..

it would need to be modified further back as in a different hole further back (NV4500 is longer) and height further back, not to mention the hole in your carpet

Not for me, but I had a friend that had one in his monster-truck that he daily-drove.  He'd make videos as he had a ton of pedestrians that didn't mind jaywalking in front of him.   He had to have those off-road tires just to get traction in all the poop that the jaywalkers dropped.

Heed Vile's suggestion and remove the fuel tank cap, then drive it for 30+ minutes or well past the time that symptoms typically appear.

I've had a triple horn manifold and one separate horn with a 13 gallon tank for years and to this day my body still cringes Everytime I touch that switch!! Absolutely my favorite thing I've ever put on any vehicle!!
Years ago when I first got the triple manifold, I stripped them down, cleaned all the casting flash and polished the internals, drilled out every fitting so I had a true 3/8" hole everywhere. I have about $12 in my system but never found a compressor I wanted to afford.
Thinking about an ac compressor setup when I get it back on the road again.

It starts up fine, getting 6ish psi at the carb, runs good, no issues. After driving for about 10-15 minutes, it starts to starve for fuel. It usually won't completely die if I use very little throttle, but the pressure drops to 0-1 and I can see that the clear filter near the carb is emptying of fuel. Initially I thought it was vapor lock (even though it felt like it was happening very quickly to be that), so I rerouted the fuel lines away from heat. I also replaced the pump because it was weeping, still have the issue.

Shifty, I believe the 4l80e is an automatic transmission. Correct me if I am wrong! I was wanting to stay with my manual/standard Transmission if possible.
