It’s a useable unit. I’ll put it up for sale in a minute, nice and cheap. I have no need for this or the other one I’ll put up for sale. A beat up LD-340.
As of right now, as far as a dual plane goes. I’ll only use the stock cast iron intake or a RPM or 6 pack. I have another Weiand on my 340 right now keeping the water out of the engine.
