order a custom cam they said,

it wont cost much more they said!so i bit the bullet(so to speak) and filled out the recommendation form thru bullet cams, i liked what they came up with so i said lets do it, for my LA 360 engine in my demon.they even called back to see if it was a magnum or not.so after paying $398 cdn and $98 cdn in duty it showed up, my brand new custom ground cam for my non existent 440 b-block. so im wondering if i send it back and get a new one for the 360 will i need to pay duty again? or should i hang onto this $497 440 cam for a possible 440 in my future?, i have an uncle giving me one in may. this isnt a roller as the price suggests, just a hyd flat tappet
At least it was obvious. I fear if lift or diration is off? I did make quick mic and my custom from comp cams appeared to be correct. And lined up right for installation. But always have that thought in mind. Especially performance parts. And might be pretty easy sell in Canada for your cam in hand? (Unless exotic) maybe a couple bucks in your pocket? Then try again?
