[DeTomaso] Dan Jones Weiand-X question

[rimov at charter.net]

Thanks for the reply:

So It sounds like the  CHI 2V 190 are the way to go for a street car with the X over say a set of Edlebrocks with the X. I believe I have the earlier version of the X. But the ports are the same on both manifolds correct.  Holley recommends the X for the use with their Commander EFI which I have been looking into. 

One last question in your opioin do you think the CHI 2V, aside from weight, are a better head than a ported and properly prepped Aussie 2V head?
