I reused my 4 Barrel cable and it seems to work fine. Yeah its a different bracket needed. I bought an installation kit from an eBay seller that had everything needed to install except the idle solenoid and bolts( cabs,manifold ,and solenoid). The kit came with a new throttle cable but haven't installed it yet.
I had already installed new 3/8 and 1/4 steel fuel lines / gas tank sender, and stock vapor separator so only used the upper lines that came with the kit.
The best part of the swap is giving away the Edelbrock 1405 and 1411 that had been nothing but a huge pain in the a$$. Good riddance!
