How to install an LS timing set

[@kejerf69]

How do you know you aligned the marks on TDC compression?

[@kyledefreitas9940]

What I always did, put a piece of paper or paper towel in that cylinder one spark plug hole and as you rotate the crank you’ll know that #1 piston is on the rise if the paper shoots out then from there just turn it until that marking is facing the top! (Assuming that you still have the heads on)

Let’s suppose I did not put cyl 1 at TDC it’s possible to not start ?

I’m having trouble finding the correct style timing kit for my 07 new body Silverado with an aluminum 5.3. I’m swapping the timing kit since I did a tsp cam swap. The cam gear that’s coming off has the 4 sensor spots on it 2 long ones and 2 short ones not the 1 long one like in the video. I’m having trouble finding the correct kit anywhere.

Yours may have the afm, in which case the cam will have a single cam bolt in the center vs the three you may need to get a complete kit to remove the afm system hope that helps

4x cam gear

Will piston 1 be TDC every single time the crank gear dot is at the 12:00 position

[@8eastk]

Do you have to put ultra torque assembly lube on the cam bolts?
