Not only is the throttle linkage chryler specific, but the and pull off arrangement is also similar to that of a ThermoQuad wherein the choke pull off also acts to slow down the secondary air valve to prevent bogging. I’m pretty sure I’ve got a 360 HD truck core if interested. It’s a non EGR with only a distributor advance vacuum port. I probably have an EGR variant, too if that’s what he’s looking for.
