Two years ago I switched my 69 340 Cuda over to a BB 470. I waited 6 months for the headers due to some "snafu" with the subcontractor they use. I must have gotten one of the last of Schumaker's headers and engine mount kits. It seems the snafu is permanent. Schumaker's demise is a terrible blow to us big block abody folks. If you are unable to find a used set of their headers or original abody manifolds (good luck-bring lots of money) you will have to use TTI's (great headers) or whoever's and be stuck with manual steering. Or you could keep your power steering and chop the sh** out of your fenderwalls and go sidepipes. If I had another nice abody and were in your place right now, under the current circumstances, I would build a stout 426 small block stroker and call it a day. It is real easy to get 500+ HP. Sad times nonetheless, because this is, after all, BBD! Clearly we need a new vendor.
