Anyone here ever used a TREX cam in a 454LSX? If so what kind of numbers did you get?

I would not do it, you would be leaving mucho power on the table.....

I would look at something like these ranges for the intake:

228-230= mild and very tame

236-240=still mild

The exhaust duration you can play with depending on what heads you use and the Exhaust/Intake ratio of the heads, plus your exhaust system.....
