Transfer Case suggestions I want to swap a LQ4 engine with a 4L60E transmission into a 1977 Chevrolet K5 Blazer, but I don't know which tranfer cases will fit. My truck currently has a 350/350 combo with a NP203 tranfer case. I don't want a push button transfer case. The transmission hump is removeable and I have an extra, so I'm not worried if I have to change the hole for the shifter alittle.

Do you mean you can't find a ECU and harness for the engine? Just out of curiousity, what year is the truck?

Actually the best case to use would be a NP241 that was available in 1988-91 suburbans, and k5 blazers. It is essentially the same case used in 88 up k series trucks. It has an excellent low range and shift on the fly capabilities and they are already equipped with the electric speed sensor. The 205 is good but extremely heavy. The 241 is a damm near bomb proof tcase.

If you are going with an lsx then you can use the electric cluster out of the 88 up suburbans and blazer and then run the speed sensor wire from the cluster straight to the lsx PCM. It saves you having to screw with gears etc to get your speedometer to work correctly. If you need a cluster or diagrams I have a spare one from when I did this to my suburban. We have alldata at the shop so it's no big deal to help.

I'll probably look for a cluster later this year, I just hope the removeable cover from the original cluster will fit. A diagram would help. Any chance you could post it?

It wont be on the wrong side because the 88-91 suburbans and K5 blazers are the old body style with a 241 and solid axle front diff. It was available in the last few years of production. You are mistaken with the newer 241 used in the 88 up trucks it is on drivers side as opposed to the older 241 that has a passenger side drop for the driveshaft. The clusters and the IP dash bezel are 100% identical between the electronic and mechanical speedometer. therefore it will drop right in and look as it came from gm. If you have a fax number pm it to me and I will send you a diagram.
