I got my truck running perfect now. It was low on tranny fluid, that was causing the higher revs.

Just too add a little note in here, i swapped a 2003 4.3 motor too a 2003 5.3 motor, the torque converter worked with no adapters or extensions needed. I used the stock 5.3 flexplate with it as well...

I just tought i would state that for future people looking too do this swap.


Now time too turbo the truck.I want more power already!!!
