Hey guys. I purchased this cam from ebay quite some time ago. Strangely, the specs on the box are different than what's listed in the Ford Racing catalogue and pretty much what information I searched online agrees with the catalogue specs.
Could it just be a misprint on the box?

Box specs. lift .453/.453 dur. @.050 210/220 intake opens -12 btc closes 42 abc exhaust opens 41 bbc closes 0 atc

Cat. specs. lift .453/.453 dur. @.050 208/224 intake opens 3 atc closes 31 abc exhaust opens 44 bbc closes 0 btc

Advertised duration is the same for both at 274/290.

Thanks.

Use a degree wheel and measure it ... the one I have measured was 207 / 221 so,
it matched neither but, was only a very few degrees different.

Awesome, thanks Randy. I kinda figured I'd just have to degree it.
