No thread? I thought I read info in a thread on this. If I remember correctly, they said it sounded like an Indy car.
I ran across a v10 ford in a small boat on Mead a couple years ago. He built a 10 to 1 stinger style header. It sounder like a Indy car. He also removed all EFI and used 2 belt driven Audi 5 cyl. distributors, and a hand made intake & carb. Very nice fab work. I think he said he was from Kingman.
