There is no way I would think about what your doing after owning and driving a 1959 Dodge Coronet 2 DRHTP with the stock 326 C.I. 318 type Poly motor and owning and driving a 1957 New Yorker and later a 1957 C 300 for a lot of miles I also had a stock 1955 New Yorker motor in a 1934 Ford Pick Up that had been chopped and channeled, that truck got me hooked into street racing in the mid 1960s It was around half fast and hard on the stock drivetrain parts
Good luck on your deal
