Recommend a cam and converter for 340
Search it on line... Catalogs are for Chevy and Ford owners...lol. Part number CL-20-223-3 for cam and lifters, 901-16 springs, and you will probably need 8 stock 318 valve spring retainers to replace the larger rotators on your 360's exh valves. I can send them to you if you can't find any closer.
