You'd need converters for the cam and crank signal. The 03 silverado has a 24x crank reluctor the LS2 has a 58x. The silverado has a 1x cam gear and the LS2 has a 4x. You'll also need wiring to convert to the sensors. The silverado knock sensors are in the valley cover and the LS2 they are on the side of the block. The cam sensor is in the front of the engine on the LS2 and the silverado has it in the rear.

Everything else will swap over and bolt right up.

Use the truck oil pan and front drive accessories and crank pulley.

So if I pull the crank and have a 24 tooth reluctor wheel pressed on what do I need to do to fix the cam situation from 1x to 4x? And the Ls2 is out of a trailblazer Ss is this what I would need to go from the 1x to a 4x cam issue

You could have the 24 tooth put on yes and you would need a 1x cam gear. The LS2 should already have 4x, your pcm in your 03 truck was setup to read a 24x crank and 1x cam

you have 58x and 4x on the LS2

Call texas speed and tell them what you're doing and they'll hook you up with what you need. Or try WS6store
