I got this camshaft some time back and have never used it because I didn't know the specs and haven't been able to find them on any searches I've done with my limited computer knowledge. If anyone has an old cam chart for this camshaft, I would greatly appreciate it if you could post it.

X28F: In my 1977 Catalog. Solid lifter.

Super radical & heavy drag. Adv duration 312/324*; 540/560 valve lift; 026/028" lash.
 
Thanks Bewy. I thought it came out of a drag race car. Seems like the car had a tunnel ram and two fours on a 340 but that's been several years back. A little too radical for any projects I have in the foreseeable future.
 
What's the duration at .050 ?
Really that's not a monster cam unless it's over 270 @.050

A catalog stage 3 cam, the 70's cam manufactures would put three cams in a jobbers catalog stage 1, 2 and 3.
In 77 I bought a Erson stage 2 solid for big block, duration and lift was a tiny step more than the hemi grind. 292/ 294 dur .488 I .492 E lift
