Ultradyne cam?

[70net440]

Anyone use an Ultradyne #3038896 cam? Lift is 485in/507ex. Duration at .050 is 231/239. The car is a race only '74 Dart, 440/727/3:91 gears. Stock 213 heads with a Weiand single plane and Holley 750dp. About 3,000 stall with 235-60-15 M/T drag radials. Rpm through the lights is 5,600. The car ran a best of 12.68/104 with a .488/.491 Comp cam in it. I need a new cam, this one looked pretty good. Any thoughts?

I've collected the camspecs of the old Ultradyne cams some time back on my site.
Just for historical purposes.

I think you can expect very close to what the Comp cam did with that Ultradyne. JMO.

x2. With the stock heads that's about what you'll see. Get a good performance valve job and a little port cleanup and maybe look into the convertor.
