340 No low end power

Theres not really much info to go by here. 340 six pack specs dont help. first the only difference is the intake and carbs on the 340 six pack, compression and cam were the same.

Theres lot sof different purpleshafts from small to huge solid cams so that doesnt really help.

The torker will kill some low end so I would start by swapping in a dual plane. How bug is the avs ? should be a part # on it someplace and you need to figure out what gearing it has in it.
