I had a customer we are building a roller for fly in from California today and had the exact same conversation. He has a LSX 454 and was on the fence about what intake / TB. For a 600HP application, we like the FASTLSX/R intake, and a ported 90MM TB. Not a big fan of the larger TBs, kind messes up driveabilty and little to no top end power help.
We run the LSX/R intake and ported TB on our 418CIs and make 601HP with a very conservative cam that makes killer (580) torque.
