    Should I swap a 383?

    I've had one in my truck for a couple of years now and I love it. It has transformed that truck from underpowered to super-powered. The stock Vortec fuel system can support at or a little above 400 HP. So I had mine built for 450. The only downside was I had to replace the rear end and the...

    Should I swap a 383?

    I put a 383 in mine a couple of years ago. And there is no comparison between the two. The stock Vortec fuel injection system is capable of supporting about 400 HP, so I had my stock engine built for 450. Brand new, a Vortec 350 was good for 250 HP. If somebody's telling you that 400+ horses...

    Too many Oxygen sensors!

    You can remove the two rear O2 sensors, then have Black Bear program your computer with rear O2 sensor delete. That's what I did on mine. No vehicle really needs four O2 sensors.

    Transmission Reccomendations for 383 500hp

    And the NV4500's 1st gear is great for rock crawling.

    Transmission Reccomendations for 383 500hp

    I've got a 383 putting out a little over 400 HP mated to an NV4500. Seems to do the trick.

    Any tricks on replacing outer door handle 88-98

    Well, I won't promise no knuckles will go unskinned, but yeah.

    Any tricks on replacing outer door handle 88-98

    Get someone with small hands to help you because there is no good way to do it. It's just too small of a space to work in. I don't know what year your truck is, but my only recommendation would be to replace it with the '88-'94 door handles, which were made of metal. The '95-'98 handles are...

    Fooling Rear O2 Sensors?

    As others have already pointed out, Black Bear can tune your computer to delete the rear O2 sensors. I know this for a fact because I've had it done. My truck only has the front O2 sensors and no loss in driveability.

    NV3500 breaking point?

    I had a '94 for thirteen years. It had an NV3500. I'm an aggressive driver, but I never had a problem with it. I'm all for the NV4500. 1st makes for a nice rock crawler gear on a 4x4. The NV 3500 does shift smoother to me though.

    NV3500 breaking point?

    I don't know. The article I read about it made it sound bone stock. But I guess it's possible.

    Fooling Rear O2 Sensors?

    I removed my rear O2 sensors and had Black Bear tune the computer. Although, the Check Engine light has never worked in my truck, so that might be a problem if you have to pass an inspection where you live.

    NV3500 breaking point?

    The 2003-2005 Joe Gibbs Silverado had a supercharged 5.3L that put out 395 HP and 425 lb-ft of torque. The manual transmission offering was the NV3500. If it's good enough for Joe Gibbs...

    Best way to prep and paint rusty frame.

    I went with POR-15 for my frame and undercarriage. I put it on over four years ago and it's still holding strong. My frame was about in the same shape yours is. (I found the truck in Nebraska where they salt the roads in the winter.) The POR-15 is about $100 a gallon and you also need the metal...

    Inconsistent oil pressure

    It depends on the modifications to the truck. That little screw can come in handy. But you're right, you don't wanna use it if you don't have to. In my case, I had to. Even with a Black Bear tune, the stock computer just doesn't know what to do with a 383 stroker.

    Inconsistent oil pressure

    These engines always have fluctuations in oil pressure, but not usually that bad. Is it idling fine when stopped, or does the idle drop? If so, there's a little torx screw on the front of the throttle body that adjusts the blade. Turn it clockwise until it holds idle around 750 or so.
