good cam for a 318

tbh i'd save the money on upgradin. just keep the 318 maintained and purrin like a kitten.

then find stuff as you go. 360 or magnum block. decent intake/cam for it. gather stuff little by little. get it all set up then one day do a swaparoo.

but like rusty said if you just want to learn the stuff and swap cams the 340 one is fine.

also if you can find an old 273 motor in a salvage yard get the rockers/rocker shafts/holddowns off it. they are adjustables... and then you could put in a solid cam/solid lifters.

oops forgot if you do grab the stuff off a 273 get the pushrods too
