XFI cams rated with 1.6 rockers
I have heard it mentioned before that the lift specs on the xfi cams are given using 1.6 rockers already. Is this true or would 1.6 rockers increase the lift more?

The specs you see are with 1.6 RRs. So to increase the valve lift to more than what you see advertised you'd need to go with 1.7s, like I did.

That's really not a good idea if you intend to twist it past about 6000 rpm. For a higher rpm combo with durability, stick to 1.6:1 or 1.5:1 with the XFI lobes.

I got the 280 xfi just for that reson so I could put on 1.5 to decrease my lift some till I get my 400 crank to make my 350 a 383 then Ill go with the 1.6
