cam install

so when putting the cam in you line up the timing dot on the cam gear and crank gear after putting the #1 to TDC after watching the intake valve open and close then rotating the engine the next valve to open on #1 is intake??? what the heck is wrong?

should just be able to line them up dot to dot. Crank dot at 12 oclock and cam dot at 6 oclock.
Go to ls1howto.com and look at the cam install......there's a picture about 3/4 of the way down that'll show you how they should line up.

+1 on ORION's advice....................additionally be patient when lining the dots up.....it took me a little time to get this right......

Cam gear only fits one specific way on the cam, so if you line up dot to dot and thread the bolts into the cam, you are set. In addition to the 3 bolts, there is a small peg that goes through the cam gear to make sure it is oriented correctly, so you don't have to worry about TDC position on an LS1.

ls1howto.com shows this in pictures and detail, as mentioned already. Good luck!

I line mine up with the cam gear at 6:00 & the crank at 12:00 for ease of aligning them. ( 180 off, but then turn the crank one turn for TDC / 12:00 & 12:00...)
