nitrous with holley 670 TBI?
I've been trying to find a nitrous kit to fit the 2" bores of the holley tbi unit but with no success. I can only find 'm for the 4.3,5.0,5.7 units with the 1 11/16" bores. Does anybody know where I can find a kit to work with my application? Thank you

NOS has a kit that will fit 454 TBI trucks, one for pre 1992 trucks and one for 1992 and later. I think you will just have to call them up and ask them which will fit.
