408 ls swap help needed. I have a gen iv 6.0 stroked to a 408 and put it in my avalanche the ecm has the DoD deleted and that's it. Waiting for tuner. But since I put it in the crank sensor isn't reading the trigger anymore. I used the stock 5.3 flywheel etc. What's going on here? Will the programming take care of this or is it an issue with compatibility?

Ok I'll double check it's the original sensor off the avalanche so is the reluctor wheel so I guess it has to be the grey one. So assuming it is grey what else could be causing this issue? It had afm which was obviously deleted when I swapped the motor but the computer guy only deleted the afm in the ecm nothing else bc he was supposed to finish the tune and programming after I installed the engine and dropped it off. Unfortunately he had some family problems and now they're backed up for a few months also they specialize in diesel engines.

That is the wrong one. it is a 1x cam gear. you need 4x.

It LOOKS like its a cast cam gear and crank gear that is just machined, if that is the case then youd just need a 4x 3 bolt cam gear

Taking the water pump off and taking cam sensor out would give you straight line of sight to it and you could tell. may need a flashlight. otherwise the camera on your phone in video mode should catch it as you turn engine over.
Honestly when even use such an unknown set anyway unless it was either left over or cheap? Hope tha helps you out. Good luck!

You cannot use an lt cam in an ls. either the gen2 sbc lt1 or gen5 lt1. That timing set is not made for a single bolt cam either. There is so much that does not make sense. If i were you id check both the cam sprocket and the crank sprocket. you can see both visually. after youve confirmed that then on to the next part.
Not trying to knock your shop but getting mixed signals from them and odd ideas they seem like they dont have a firm grasp on the ls stuff. Crane has ok cams, but for 1k for just cam and lifters that seems wayyyy padded for profit. our ls7 lifters are 95 and cams are 385. springs even are like 130 - 289. so thats still not 1k.
