I can't find any specific documentation on it. Google popped up something from Schneider cams that may be it.

Regardless, my guess is that it's a 290/290 advertised duration. If you have a degree wheel, you can easily map it out and get all the specs.

could be an old Crane Fireball 290. Could be an old Wolverine 290/290 with .505/.505 lift. i had this wolverine cam. Later Crane bought out Wolverine and they changed the specs of the 290 cam
Matt.

P.S. you should post a picture of the cam. You will be surprised how see it might trigger someone's memory.

FWIW, I have an ANCIENT (like late seventies) Comp Cams 308H hydraulic for BBM here, it is stamped "308H" on the timing chain end. I also have an early eighties Comp Cams catalog, I will take a look and see if there is a "290H" hydraulic listed for clevelands.

Looked in the catalog, 296H no 290H?? I have later mid-eighties Comp catalog I can check, but it will take a while to find that.

I found this write up. maybe it helps?
https://www.7173mustangs.com/thread-351 ... kinda-long

By the way these cam specs are the same as the Wolverine cam i posted in this thread. Wolverine cams was a Crane Cams off the shelf cam you could (and I did) order from Autozone. When Autozone was a cooler place to go, I could walk in and at the performance isle they use to have the COMP, Crane, Milling and Wolverine Blue Racer cam catalogues just sitting there to look through. I ordered the Wolverine 290/290 .505/.505 cam. Great stock rebuild cam with real nice low end mid TQ. I think I went 8.4's in the 1/8 mile in my 70 Cougar with the Aussie 2v heads, c4 w/2500 stall and 4.11 gears. Dynoed 250hp@5800 and 320tq@2800 at the wheels with a Weiand X-CELerator Intake Manifolds 7516 and Original BG 650 Speed Demon. At that time I also had a Duraspark distributor but with a brand new "BLUE" module. I guess it had a built in rev limiter cause that's what it did every time it got to 6000rpm.

The valve train utilized an over-the-counter Ford hydraulic camshaft, part number D1ZZ-6250-BX, which was a very popular street cam in its day. It was a hydraulic version of the Boss 351 camshaft, a perfect street camshaft from the perspective of maintenance and powerband. Almost every cam grinder and hi-performance parts vendor offered a version of this cam in their catalog. Its still available today as Speed Pro #CS173R or Melling #24224. The cam specs were:

290°/290° duration @ 0.004"
0.505"/0.505" lift
Exhaust valve opens at 84° BBDC
Intake valve closes at 74° ABDC
62° overlap
219°/219° duration @ 0.050"
114° lobe separation angle
Intake lobe centerline = 109° ATDC
