I'm not sure but I beleve this will work on the LT1

The mounting holes aren't in the right place... Edelbrocks use brackets that bolt onto the bottom of the intake whereas the LT1 rails bolt into the top of the intake without brackets. They could work if you were to fab up some mounting brackets to mount them like the stockers, but you can modify the stockers just as easily...

 

my modified stock rails, -10 split into two -8's at the back of each rail, -6 returns to the FPR
