Doubtful. I make mid to upper 400 RW #'s, it takes more than a few odds and ends to pick up 50 RWHP. What is done to your heads? Any flow sheets? Or are they basically stock 5.3L heads?

IMO, you're going to need every last little bolt on, a cut out, a set of heads that flow around 300cfm - yet retain good mid lift flow, and a cam that matches.

Remember - peak #'s aren't everything. Power under the curve is where it's at.

Nice numbers. Are you getting all of what you could have so far to the ground with the suspension you currently have?

Look into a fast intake and a cutout those 2 alone should boost your hp #'s decently

Get the power to the ground. A lot of potential untapped at the level of power your car already has with the basic stock suspension.

As mentioned:

#1 - a complete power curve rather than the peak is what you should be looking at.

#2 - if you can't put down the power you have now, why worry about more? I'd take a look at suspension upgrades first.
