what is largest cam for 340 with factory 10.5 flattops????????

Usually when somebody asks what is the biggest cam they can put in , they are looking for the sound of horses in gallop the easiest and cheapest way they can get it . Motor builders know you need the package to make max power. This guy just wants the sound of the cam first . with a little more power second. There are alot looking for just that for cruisers. To idle them into the drive-in
