depends on the years of the said transmissions. The stall speed will most likely be different regardless but the effects of that could be inconsequential depending on your application.

BOLT RIGHT UP is only half the battle. The question of year needs to be addressed, as all 4l60E's DO NOT interchange.

the 4.3 will have a higher speed convertor than the v8 as stated. There were many changes to the 4l60e thru out its production.
As stated, it depends on the years, the electronics changed throughout the time period.

Yes if it’s a late model it will fit I changed mine. I have a 98 s10 and my engine went down so I dropped in a. 5.7 v8 vortec and it mounted up to my transmission without any issues. A 4.3 vortec is identical to a 5.7, in Ls family. They use the same pistons only difference is a 4.3 is 2 cylinders shy of being a v8. They have the same exact bolt patterns if it’s a late model like your engine. Now if u go get old 350 or something has a carb then no it won’t fit. Different bolt patterns. But on 4.3, 4.8. 5.2, 5.7 they have the same bolt patterns. I’ve changed out several over the years that’s what I do is mechanic work for a living. If u have any questions or need help with something feel free to get up with me. But I also didn’t have to change bell housings like some ppl say u have to. When they doing that then they aren’t getting the late models to match right some other v8s won’t mount up but a 5.7 will most definitely mount to a 4L60E. That’s what the combo was in the z28 Camaro 5.7 LS with 4L60E transmission. Also they use a LS-style 300mm input shaft.

That’s a lot of writing to reply to a 13 year old thread. Please don’t bump dead threads.
