The L92/L76 intake WILL NOT FIT the 5.3 heads. It will only fit the L92 heads and the L92 heads will only fit a 4.000" bore or bigger motor . Also a 90mm throttle body WILL NOT FIT the stock truck intake.

The best bet for getting a 90mm on a 5.3 would be the SSR intake, or a FAST 90 would fit with some accessory mods.

And just to clairify. The L92 intakes only fit the L92 heads designed for the 4.0 or larger bore.

There has been talk of a smaller version I duno where that went though
