I replied to your question on your thread. I am not pushy so I didn't try and sell you these. But I had them on my 3.4 whipple with crusher intake. The crusher intake had to get milled a little bit to clear. That's the only issue I had with these. And I would assume its cause of the shear size of the crusher intake.
I had them on my car for 5 years and 13k miles. No issues beside what was mentioned.
Yeah sorry, i'm no help. Only 100% sure on 3.4 w/crusher. As I know of 3 including me. Other 2 are on different platforms. i.e Marauder and a lightning. But I am sure the info is out there. just gotta search for it. I would but I am shoulder deep in turbo build knowledge at the moment.
