Has anyone done a LS1 TB swap yet?

Once you do this, please post some pictures. This is quite interesting.

And what i did to make it fit on the stock air inlet was cut off the retaining tabs, and then grind down the plastic to make it a smooth circle. Go to Lowes and get a 4" to 3" flexible coupling and wala. it all fits. IT will take quite a bit of force to get the 3" side on. and make sure to get a hose clamp for a 4-5" because it will stretch the 3" side to about 4.5"

Running into a bit of a issue making the TPS sensor work... gotta keep messing with it.

Seems like it would be really easy to make that fit with an open element filter

Did the shaft on the 350 TB have a big enough slot for the 5.3 blade?

Well i got it all working and running. I still have to do something about the tps sensor. i have it all together and where it should be with zip ties holding it on..... i know ghetto but it works for now til i can find the right one or... ultimately have to put the other tb back on.


Here is what the stock sensor is....

is it possible to weld on the shaft and grind it down at the right angle to fit the TPS?
