Ok so after getting used to this truck here are some issues I have noticed.

1. There is a noise when I put the truck into gear R,D,2,L, but not in P, or N. I think it is a broken tranny or engine mount.
2. The LSD sucks big time, the only way I can get it to work when one wheel is off the ground is with the E brake, on the street it slips bad and makes noise like the lsd is worn ,although on wet roads or dirt it will spin both tires

3. The auto tranny is pretty cool, with the exeption of when I am doing 60 or so, if i try to pass a car it will shift out of 4th to 3rd, but if I floor it it will go from 4th to 2nd, and almost over revv the engine.

4. Here is my biggest issue, the stock G54B is gutless as hell, no low end torque to speak of and does horrible with the a/t climbing hills, and in the sand I cant get enough rpm in 2wd to get it to move, as my 22R toyota will rip the shit out of the sand and will climb hills no problem.

I am happy with the truck, I like the way it looks and it rides pretty nice, its just the engine i cannot stand, as when I hit higher RPM it will start knocking, and it has almost no power (May be fixed with a 32/36 weber not the knocking though) The tranny is awesome, i like the fact I have room in the truck and it has nice amount of torque, and the LSD i think it just needs some work.

So since I now have a full time job I may just be able to do what I want with the truck, I really want to know if I can swap a 4G63 into this truck project0g.com says that the A/T is a narrowblock behind a 2.6, but others I hear its a wide block. They say the km148 will stand the power of a 4g63t, and will transfer it nicely, but that the 5 speed manual km142? bearings will not stand up to the RPM and power of a 4g63t. I am curious as I am disappointed with the performance of the 2.6 (May just be carb related though)

Thanks in advance for any input.
