    If I am thinking of the right intake, that is a pretty old design that is quite good actually.  Seems like they were a very good street intake and not so much a high rpm strip intake.  Also seems like they produced decent power from off idle to around 5800 or so.  I might be thinking of something else, but that seems right.....   :bigshades:   I am sure other will chime in with the exact figures and correct my old memory....lol....    :thumbsup:

     The LD340 is an old design too. Made for trans am type driving where the throttle is feathered a lot. Is the LB4D a copy or updated version? :clueless:

    I think LD340 has intake runners that are the size of 360 heads, and I think the LD4B has runners the size of 318 heads.

     You are correct , the LD4B is one of the very few true 318 intakes with the smaller ports
