Default 1999 firebird, 5.3 lm7 engine swap question

im swapping out the 3.8 for a 5.3 from a 2000 surburban and i was wondering if anyone knows if the truck intake will work with the swap cause of the clearence issues with the cowl/firewall since the intake is taller

You will need F-body LS1 Accessories & Oil Pan, K-member & Mounts, Steering Rack & Linkage, LS1 PCM & Wiring, and a Car Intake.

Auto or Standard?

Bellhousing on a V6 Auto doesn't come off..and you will want a T56 if you are a manual.

The Truck Intake is really tall..I don't think it would fit under the stock Hood of a car.

Truck intake is tall. gonna say it will not fit under a stock hood. Also get the LS1 accessories. Having the alternator up top looks terrible in a car especially with a car intake
