    Swapping from dual to single headlights 1984 Dually

    Depends on your perception of cheap. Amd over 300 plus shipping by truck. Some on ebay for around 200 but who knows the quality and most add shipping(180 +/-) Swapping it isn't set in stone. Just weighing the options.

    Swapping from dual to single headlights 1984 Dually

    Got my truck down for paint and 5 spd swap. Original 4 headlight support has seen better days. Have a good single light support from a 85. Will be getting buckets,lights and trim new. Question is will the grills interchange? Anything else i'll need? Thanks

    Stroker 454

    Starting off with a gen 6 block would make things a lot easier. Main oil Gallery moved up to make more room for a stroker crank. 4.5 stroke crank would make for some really short pistons(9.8 deck). Race engine maybe but i would never go that route in a street driven engine. 504/505 is a pretty...

    NV 4500 oil

    Swapping my Dually from a 4L80E to a NV4500 manual trans. Most use Redline MT-85 or 90 oil. Can't get it around where i live without ordering it. Any other GL-4 rated oil that can be used? Been looking at John Deere Hygard as it is GL-4 rated. Run it in all my race transmissions and it holds up...

    Early buick th400 question for the trans guys.

    Is strange that it has a bop housing. Could be that someone swapped cases. Is definitely not a switch trans. Maybe someone swapped housing But the tag looks undisturged. I got a couple other valve bodies that I will use and another bop case

    Early buick th400 question for the trans guys.

    Have a one year only 64 Buick th400. Has only a 5 position selector(p,r,n,d,l) instead of the usual 6 position(p,r,n,d,2,1) selector. Still a 3 spd trans. Question is the internals any different than the normal 400? Can I swap a later valve body onto it? Trans is clean inside but still will be...

    th400 electric speedo

    Correct me if wrong but that is the wiring that goes to the electric kick down. Speed sensor is in the tail housing.

    th400 electric speedo

    Got one of those because one review said it would work in a 400. Nope, hold down tab in wrong spot and it won’t even go in the hole.

    NV4500 + 12” clutch and pressure plate???

    I used the aa housing and 12 in clutch. Fits fine. AA did say that some will fit and some don’t. I used a autozone replacement diaphram clutch. Flywheel is the same as 11in clutch so any application that uses a 11 in clutch will work.

    Center hump

    Bingo, looked thru some old posts on Facebook and found some pictures of the 85 4 spd truck I had.

    Center hump

    From looking closer to the picture of the 87 4wd /auto there looks to be an indentation where a 4spd shifter would sit so I would agree that they are the same. Parted out a 85 2wd/4spd a few months ago but deleted all the pictures after I sold the cab.

    Center hump

    Thanks for the replies and the pictures. Clears up a lot of questions. Only question I have is there any difference between the 84-87 high hump with a manual 2wd and auto 4wd except the obvious hole placement for the shifters?

    Center hump

    I realize that. Got a high hump removable pan and it doesn’t fit the floor contour on my 84. Question is are the later floor pans different With the non removable hump?

    Center hump

    1984 c30 dually. Swapping to a nv4500 from a auto. Got a removable hump from a earlier truck and it is not even close to matching the floor pan. Correct me if I’m wrong but even the high hump floors from that year(84) was not removable? Is there that much difference in the floor pans? Local yard...

    Engine swap for street and towing

    For me the 8.1l 496 is a better option. Bolts right in and you can use your drive train as is. Use 454 exhaust manifold. Upgrade to a 4l80E and cruise at 70 no problem. Kodiac or van front drive would be nice but not totally needed. There is aftermarket brackets available. 6.0 ls engine would...
