Thanks moparborn. Im pretty sure a Weiand is in my future. My obsession is the dual quad cars of the late 50s early 60s-383s 413s hemis from all eras, Olds and Buicks- 409s with dual quads. So cool that it was available from the factory. Im disappointed Edelbrock will not make a dual four manifold for the LA. The unit they made 40 years ago was for the 273. Im checking ebay moparts and A Bodies often for a used 340/360 tunnel ram.
