    Picked up a 700R4

    I scored a 700R4 today at a local yard. I went yesterday for TBI fuel lines and found the 1990 1500 with the drive lines out of the way and transfer case already dropped. I’m swapping a TH350/203 to the 700R4/203. I’ll go through the 203 when I drop it. The 700R4’s fluid is bright with no...

    torque converter lockup in any gear

    Can someone explain to me the advantages of wiring a torque converter that can be locked in any gear? Specifically, I just bought a truck that has the 700r4 wired so that it will lockup in any gear with the flip of a switch. Other than being able to stall the truck just by stopping, why would...

    Transmission cooler?

    Hey guys, any suggestions on what type/brand/model of transmission cooler would you recommend? I’m currently running the stick radiator cooler, but I wanted to get an external one to better keep my TH400 cool. Fan/no fan? Finned? Aluminum? I would like to keep it affordable, but quality is...

    Engine swap in my '85 Blazer

    I have an 85 K5 Blazer with a 305 4bbl Q-jet and a 700r4 k case 4x4, all mechanical hookups. I picked up a 350 tbi with most parts to make it work off a 95 Blazer, however a lot of the research I have done makes it seem I wont be able to use the ECM with the 700r4? Is there an adapter I can use...

    Wes's Burb build/update/maintance

    So after converting my 77 sub, sbc, q jet carb, np205, 4.10, 33, to use a 700r4, the truck ran horrible up any grade in 3 and 4th. I pulled the carb off and ran spray carb cleaner and compressed air through all passages, new gaskets, etc. Recheck/set adjustments. Truck ran pretty good for @ 200...

    Too Nice to Tear Up

    I bought this 1978 K5 Blazer, in July, 2006, from the wife of the second owner, after he died. I was looking for a Blazer to cut up, and turn into a "rock crawler", so a K5 for $500, seemed like a good start. I went to her house, and out of the garage came a really nice, not rust free, but...

    I have a 99 k2500 suburban with a 454/4l80e/246c. I am sick of replacing the transfer case. It's a crappy job on a good day with where I'm working. I happen to have a built 700r4 with a ford pattern (driver side drop) 205. Mechanically, I have no issues with the swap. It's a daily driver and my...

    Offroad 1979 K10 SWB "Jolly Green Giant"

    I call my truck "The Price Is Right" for a couple of reasons. First off, I traded a friend's father for it. I fixed his wife's Pontiac, he gave me this truck. The second reason is because I am sourcing as much of this build as possible from either junkyards or classifieds or parts trucks, etc. I...
