camshaft for mild 340

without knowing his compression you guys are pissing into the wind
all could be good suggestions depending
the summit is an old crane/ cam dynamics grind
melling could be a stock 340 or any variety of chevy copy
voodoo line works but which one depends on your build and desires
btw lope and broad power range are incompatible given what you want to change- go for power- change your mufflers if you want sound
post your compression, gears carb and headers and you will get another round of opinions that are closer to the mark
stock 340 cam in low compression motor leaves a lot on the table without converter and gears
