Cam question for crate motor

goinbroke2 · 12-14-2013, 01:18 AM

Building a 302 crate motor which calls for the 303A cam (.498 lift) and I just came across a good deal on a 303B cam (.480 lift but more duration)
I know the duration rule is unlimited and I'm waiting for a price from bullet for a proper .498lift stocker cam, but this would be a cheap alternative just to get it on the track.

So, can I run a .480lift cam when it calls for a .498lift one? I know you can't go over, but can you run under? (I'm thinking yes but want to confirm before putting out an offer for it)
