I am using the Brian Tooley Racing Stage II Truck camshaft in my LS1 .
On the Dyno I had 355 RWHP. Using shortie headers and an LS6 intake.
I just broke into the 400hp at the crankshaft.
My Camshaft (SPECS: 212/218 .553”/.553” 111)
Fairly mild cam but it works perfect in my book.

To achieve 96 more hp i.e. 450HP is another step steep into the pocket book.
Higher compression
CNC heads
Long tube headers
Intake manifold.
Injectors.
You can get there but it will not be inexpensive.

Cheers
