The 70 challenger that dad recently got has a 318 in it bored out so it is fairly close to a 340. The previous owner installed an Edelbrock LD340 4 bbl intake on it and has headers for the exhaust. We are looking to get a somewhat stock appearance and were hoping that the 340 exhaust manifolds would work on this car. Dad found a 1970 Chrysler cast iron 4 bbl intake fairly cheap and also has located a correct 340 snorkle-less air cleaner housing as well.

Can this be done and fit correctly or no?

Thanks for your answers.
