340 Build advice needed!

cant give much more advice than what you already have got, but i think that cam your looking at is a pretty powerfull piece, i have a comp extreme energy roller, the next size bigger than the one you are looking at and it has a very nice midrange and topend, alitle bit rough at idle but as soon as it starts making power it realy ran nice, its a few years since it ran but i miss it everyday, very streetable as long as you have alitle more converter than stock
