sounds fine in the vid to me..

They're making noise, but it sounds about like a 1.7 should sound on an already pretty aggressive cam lobe. My 1.6 Pro-Magnum rockers are noisy too...have about 60,000 miles on them. I say run it.

Yeah,plus having thin steel valve covers helps to amplify the sound. It's a noticeable difference across the powerband now though....

....now that it's running on all eight cylinders!

Every set of 1.7s ive ran or heard have been noisy

My 1.6 Scorpions with an FTI cam sounds very similar.

Ed has a disclaimer on the cam card though....the cam will have a very mechanical sound because of the aggressive grind. I readjusted 2 or 3 times when we first got it going and chalked it up to the mechanical sound.

yeah mine were the same way on my last two anderson cams. sounded like two squirrels having a walnut battle under the valve covers.

My stock 1.7's were never noisy though. Of course the only cams that they ever beat up against was a 'b' cam in my car and a 'e' cam in PWT

Is he talking about walnuts or WALsNUTS

My old setup with stock cam & Crane 1.7's was pretty noisy. I put in a "B" cam & used SVO 1.6's and it doesn't make half as much noise. Of course I used new lifters...
