Hello.
If your engine is going to be all drag, I would consider a regular Fk89 or the CB version. The Web 251 seems to be a hairswith lower than the Fk89. But if it was for a semi street car I would take the 251, as it is somewhat more usable in the lower rpm and also idles nicer than the 89.

The 0,630" on the Web is @ 1,5 ratio.

Like I wrote earlier. if you want to go all out  in that range, try the CB version.

I have a Web 251 in my current 2332 cc and it measured out to 0.590" with 1.4 rockers (cam comparison chart says 0.421" at cam and 0.588" with 1.4's).

Cam specs show Webcam 251 to have a little more lift than Engle FK89, slightly less "advertised" duration and slightly more actual duration at .050 lift. In my motor with Berg "so called" 1.45 rockers I measure almost .660" lift. Car ran 10.44 @ 127 -1575lbs. Wayne
