Tdc ???

[akart]

First let me say that the truck runs perfect. I am adding a Voodoo cam and a bunch of other stuff. I start and check the TDC and with the timing marks lined up on the cam and crank (cam down and crank up) the compression stroke is on cyl #6. Me thinks the cam is 180 off. I am thinking I will install the new DUI distributor the same way (as is) Is this OK, any thoughts. If I install the distributor 180 from what it is the compression stroke at TDC will still be at #6 (I think)
