Up for sale is a 1969-1971 dual 4bbl base plate for a Mopar 426 Hemi engine, for non-shaker application. I got this a swap meet, and the seller said it had been notched for tall breathers. Someone has also messed with the carb openings. If you are handy, this looks like it might be a fairly easy fix for a stock application. It sits nice and flat, and is not twisted or bent, and doesn't cost $700.00.
Be sue and use the "up close" feature to see the exact condition, verify your application, and ask questions prior to purchase.
