ls1 in iroc ?

will the stock fuel pump and stock torque arm work on the ls1 4l6oe in my iroc and if the pump will work do i have to get a regulator

The stock pump might work but I'd upgrade to a 225 lph pump. The regulator would come with the LS1 induction setup.
You may need to change the tail housing on the 4L60 to get it to work with your torque arm.

thanks for the help
