Recently picked up a 2001 5.3/4l60e out of a silverado. Too cheap to pass up. Anyways, i was wondering if the stock exhaust manifolds on this engine will bolt up to my old exhaust y pipe. Can i also use my 1996 intake for this motor? And lastly will the 2001 4l60e fit into my old 4l60e's place without changing the driveshaft or tranny mount? thanks!

looks like the 2000+ 4l60e's are about 3/4 an inch longer than a 1996 model. So, guess im rolling with my stock tranny.

I just swapped a turbo 6.0 into a 99 c2500. The stock exhaust manifolds fit perfectly using the dirty dingo mounts with the trans in the stock location. I'm not sure if they bolt up to the factory y pipe but I believe you can make it work pretty easily or use the y pipe from the donor vehicle. The dirty dingo mounts are adjustable so you could slide the motor forward 3/4" and use the newer trans in the factory trans crossmember.

If I remember correctly, when I did the 5.3 swap in my '94 u can use the OBS line, get a universal fuel line from auto part store with fuel hose clamps and connect obs hard line to 5.3 fuel rail. All of the information I got for my swap was from LS1 truck.com and I did my own harness using LT1 swap.com. 4 years and 12k miles later, no Issues.

I also used dirty dingo mounts. I went from a 4.3 V6 to 5.3 LM7 and I could not use the Y pipe in anyway. U can slightly mod ur V8 Y pipe to use with the 5.3 manifolds. No u can't use intake of ur motor to 5.3, they are 2 totally different designs. In regards to trans, yes u can use the 2000 & up trans. Your frame rail should have extra holes from the factory and you can just move trans cross member to them. Or if you are using dirty dingo slider mounts, you may not have to move that cross member.
