Default Need some help with future mods

Okay well the car made HP= 235 TQ= 341,
now all that has really been done is the forced air intake, which had very little if any air being pushed into it. The 1.6 Pro Mag roller rockers, muffler eliminators. Thats pretty much it except for the MSD. I am working on cutting back the walls on a spare intake, hopefully push that peak up past 5,000 rpms closer to 5,500 rpms. I have an AFPR to add.
So now to the question, what can i do to make more HP, i am pulling the manifolds off to grind out all the excess welding in the port, and plan on taking the pre-cats off or gutting them and putting on a high flow cat. Anything else? comments and suggestions are greatly appreciated. Thanks guys :cheers:

The hotcam is not designed the for L98's power band. Real power comes from the whole package: intake, heads/cam, exhaust. How much power are you looking for?

I am not looking for anything absurd, just as close to 300 as possible without tearing into the engine, right now 235 isn't that bad, but would like a little better numbers, even if i can pull that up to 260-270 and keep the torque around the 340 area i would be happy,

My current plans are to to the intake mod that involves cutting the dividing walls out of the manifold
Then to do the AFPR
Then remove the pre-cats
Then maybe do cam and TB
Anyone with similar set ups, or maybe even a guess as to what i might have with those mods?
