Need a little help making a decision
 

I have a DSS 302 stroker motor built for 800 hp however I'm at about 485 rwhp. I have Paxton 2200 s/c, Gt500 fuel pump, 80lb injectors, 10% overdrive crank pulley, 3:73 gear, coastline d/s, TCi trans. and convertor. I want some more rwhp, I not sure what to add, more boost, cams with long tubes. What would be the best bang for the buck. I would like to be around 530-550 rwhp.

If you've got the built block, more boost is the fastest path to more hp.

What type of throttle body do you have? That would be your next issue I would say before adding boost, which is, what I think you should do.

It's stock, Ford racing throttle body and more boost is what I will probably do first.

Look in to the Whipple monoblade and boost up son
