I am ready to install an LS in my 68c10. Currently it has a TH350 but i am just at the point of putting an overdrive trans since i already have the terminator x max. Truck is 3400lbs with 3.73 gears and 26.5 tires. It will be my weekend cruiser. May do a good burnout hear and there and quite possibly 1 pass at the dragstrip just for fun. Motor is a lc9 with BTR Truck Norris cam. Tbss intake w/dbw and speed engineering headers. Dont imaging anymore thatn 450 crank hp. So this leads me to findind a 4 speed trans candidate. 4l60e or 4l80e?

If you were to decide to order one i ma a few weeks out about 4 at present, The best way to contact me and set up is via facebook You can also look over all my builds and what goes into them via my photo albums. Every build gets one so people are not only told but can see what they are getting inside.

frank, you are definitely on my list for a 4l60e. You must have plenty of cores. And a 4l60 with shorter first,second and longer overdrive than a 4l80e sure makes sense in my case

A THM200-4R Transmission would be the least amount of work to swap...

And Frank should be able to handle that if there is a Core available.

FranksCustomTrans

Honestly they have become like finding a needle in a haystack the 200-4r , I like the trans rather enjoy doing them just cannot get half decent cores anymore and locally when they do pop up people want 400 500 and more for a core.

FranksCustomTrans

Cores on the 60e are not an issue at all . Have plenty and access to plenty more,

1 more question frank, convertor. Do you supply or have a brand or recommendation for a 3k

FranksCustomTrans

I dont sell or supply but generally refer to circle D or FTI for stalls. Yank is also good .
