Default Intake compatibility- L84, LT4, and LT1

Is there a source showing what components are interchangeable on the new Direct Injection engines? Will the LT4 supercharger bolt on to a 5.3 L84? Will the LT1 intake bolt on a 5.3 L84? I have not found much in terms of what items can be swapped.

Yes, the LT1 manifold will fit on a L83 (5.3). It is a popular upgrade on these new LT's. I have a 2014 Silverado with full bolt ons. Next upgrade will be the L86 intake manifold and throttle body though. The Lt1 intake requires either a pulley change or throttle body bracket to reroute the angle since the LT1 snout points down, which is right in the way of the belt pattern on the truck accessory

Supercharger will not. You need adapters. Iím pretty sure the head bolt pattern is different on the LT4 heads vs the Lt1 and truck motors.

As for L83/4/6/7 these motors in 2019 only got the upgraded DOD so the intakes are interchangeable still. Lt1 will bolt right up. Check out my build thread, i stuck One on my l86.

Search Swaptime on YouTube. He has a good video in regards to fitting and selecting the correct lt4 blower on a 5.3.
