5.0 B2 roller camshaft

I pulled a motor apart that had lots of performance parts on it and found the hydraulic roller cam that was in it was marked "B2" on the end. Does anyone know where to find the specs on this cam?

Any information would be awesome.

Thanks

I am guessing that it is a stock GT cam? I think I've heard that they came with a B cam.

maybe. Just didnt make much sense. After market headers, ecc, programmer, roller rockers, etc... Why would he have a stock grind on a motor like that?

Money? I know my X303 cam says X303 on it. I have the Z cam ready to go in next, in the 65 mustang of course.

I checked two HO roller cam's and a 95 Cobra roller cam out in my shop, and they all have different markings. The 85 HO roller has IJ2 on the end. The 86 HO roller has J22. The Cobra cam has I:87 stamped on it. It also has a date 05/07/95. I don't know what B2 may mean? The B303 is a popular hot rod cam for 5.0's. There was a precursor of the B303 called the B302 back in 85/86. The B302 was the same as the B303 except for tighter lobe seperation. The B303 is 224/224 degrees @ .050, 284* advertised duration, and 480/480 lift with 1.6 rockers.

I know that crower makes a b-22 cam which is what they call a "stage 2" cam but I cant find another number on this cam to justify calling it a b-22. I will have to spec it out with a degree wheel probably and see what it is.

Thanks.

PS I am going to run a e303 cam in my '88 bronco, (5.0HO motor/10.25-1 comp/AOD tranny/MAF conversion) any thoughts on this?

I use an E303 in my mustang. It's an excellant cam with a very wide power band. I think it will be okay in the lower RPM's in an automatic Bronco, even though it makes the tach spin up quickly. The midrange is strong. The E303 will cause a searching idle, even with mass air, so don't become alarmed if it's idle is a little rough. Set the idle speed up a little higher, and it's alright. The E303 idles fine with a carb.
