LD340 MODIFICATION OR NOT?
Personally I would not modify it, I was looking for that intake down here in Ontario and if I could find one it was $600-700+ and dirty with stripped holes. I ended up buying a RPM Perfomer off of Amazon for $500 shipped. And that was with tax and shipping.
I believe that the Weiand 8007 was a little less. The LD340 is a very desirable piece and once you modify it...it worth a lot less.
Just my opinion, but it is your choice.
