I used a 340 Torker intake on a 1968 340 motor that went into a 1965 Baracuda that didn't perform well but the owner used the stock 273 exhaust manifolds with the stock single exhaust system instead of buying a good set of headers like I told him that motor needed
All motor need to breathe to perform well The single plane intake compared to a decent dual plane will depend on the cam, converter, rear gear and owners likes and dislike on how they like that intake
