    Good Source for NV3500s

    Can't recommend a rebuilder, but when you get you're new NV3500 I would use Amsoil Synchromesh fluid. I have tried GM and Pennzoil synchromesh, but the Amsoil is the smoothest shifting fluid I have tried. Mine is getting worn out and the Amsoil fluid made a noticeably smoother shift with less...

    1998 C1500 speedo recalibration for gear swap.

    So the 1998 c1500 I bought has 3.73 gears in it instead of the 3.42 that it left the factory with. It was like this when I bought it, and I plan on keeping the 3.73 gears since it helps the v6 when towing. The speedometer reads off, and I would like to correct it. I work for a dealership...

    Vortec fuel Pumps

    As far as I know, the delco pump is the best one your going to find. It should have a 12 month warranty, can't you get a free warranty replacement?

    98 Chevrolet C1500 4.3L. Will plain AC Delco Copper plugs, be sufficient in my engine

    My 1998 came factory with iridium plugs. The copper plugs don't last long in the newer vehicles with high voltage ignitions. I have seen Delco iridium plugs come out with over 100k and still look good enough to put back in! The iridium plugs also have a finer center electrode and a tapered...

    Aftermarket ignition coils

    Yep, been hearing of several failures of the MSD coils. Stick with a Delco or Napa/echlin or Standard Motor products coil. They are build to OE specs.

    Dang nabbit that boy is crazy.. A i4 in a suburban!?!?!

    I knew of a guy that put a small 4 cylinder out of a combine into a Ford Ranger. It was not fast, but he claimed it got 40mpg. I think it only went 60 or 65 tops. It always interested me. On the original posters swap idea, It is neat, and I always liked unusual engine swaps. With that big and...

    Carrier bearing

    Take it to a drive shaft shop if you have one in the area. Last time I needed one replaced, I took it to Fleet Pride, and I think I was out the door for $80-90 parts and labor.

    NV3500 input seal replacement

    Just in case anyone else needs to do this, I did it and it was pretty simple. There is a front bearing retainer plate that goes over the input shaft. That houses the input seal. You just unbolt it, pry the old seal out, drive the new one in, and apply sealer to the bearing retainer plate and...
