I have one I’d sell
It was not a take off, it was a Ford performance kit with the Cobrajet twin 65
I’d sell with that and a BPS ported/oversized elbow and bps 2.38 pulley and ID 725’s if you want a full 750hp bolt on combo.
All the parts have like 6k miles on them.
I’m not giving them away though, so if cheapest is your goal, I’ll let other guys step in.
