so I’m looking at the comp cams or voodoo roller cam and looking at the spec card it doesn’t specify 1.5 or 1.6 rocker ratio. Building a magnum engine with eddy heads and not sure if I need to do the math if the cams are based on 1.5 or if the specs are for a 1.6 and no need to figure out the math.

I believe they're 1.5.. usually they'll specify 1.6 i've noticed.
 
take the lobe lift and multiply it by the rocker ratio and see if it matches the valve lift..

and you will never have to ask that question again...lol
 
Thanks for the replies, helps a bunch. Looks like I’ll go down one size and figure out the ratio. Being the magnum a 1.6 ratio the ones I was considering will be too much. Going down one size with the 1.6 should get me back to what I was looking for.
