Re: X1 cam specs are way off!!!! 230 duration with 609 lift <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I would NOT do it with milled heads! I think the TR230 barely clears. Im not for certain though.

Re: X1 cam specs are way off!!!! What numbers are you looking at on the cam card? Multiply "lobe lift" by 1.7 to get lift.
The card should say something like...
------------------intake exhaust
duration @ .05----230 227
lobe lift---------.3476 .3360
lobe separation---112.0

I have no clue why comp printed the gross lift specs with a 1.75 rocker ratio. anyways you're good to go.

Re: X1 cam specs are way off!!!! I wouldn't worry about it too much. My specs I believe on the cam card on mine were almost the same. I have milled heads to 10.8, but my clearance was ok. You definately should check clearance though with milled heads.
