If you attempt to put a vortec engine into a vehicle with a NON-vortec computer, you'll have more problems than you care to deal with.
You can put the Vortec in it if you have the wiring and ecm to run it. or you could use the Vortec heads and an aftermarket intake and really wake up your engine. The vortecs use a roller cam.

The primary difference between the 350 V8 Vortec and the 305 V8 Vortec Chevy engines lies in their displacement and power output. The 350 V8 has a larger displacement of 5.7 liters, typically producing more horsepower and torque compared to the 305 V8, which has a displacement of 5.0 liters. Additionally, the 350 Vortec often features enhanced performance characteristics, making it a popular choice for applications requiring more power, such as towing or performance vehicles. Both engines use the Vortec design, which incorporates advanced cylinder head technology for improved airflow and efficiency.
On this engine I recommend you use an AC/Delco filter.
Use 91 octane or higher octane rating premium gas for the 2009 Lexus RX350
Yes, you can use a 350 intake manifold on a 5.7 Vortec engine, but it requires some modifications. The Vortec engine has a different port design and requires an adapter or specific intake designed for Vortec heads to ensure proper fit and performance. Additionally, be mindful of compatibility with other components, such as the throttle body and fuel injection system. It's always best to consult with a performance specialist or mechanic for the best results.
Stick with Classic 350 on regular gas. I'd go with an 87-up 350. The one-piece oil pan seal and raised-rail rocker covers are less prone to leaks. no by fare use a new motal better evry thang

Regardless of the block, you have to use Vortec heads to use a Vortec intake.
