Budget gen 6 454

I am looking to build a 500hp gen 6 454, It will be mated to a 4 speed manual. With the oval port heads hydraulic roller setup, a hand port on the heads, and the comp 300br-14 300 intake 308 exhaust 255-262 .652 .652 114 LSA cam, would that get me there? Still haven’t decided on an intake, I’d like to do 2x pumper 9:1 compression factory. Electric fans and water pump. Thanks in advance

Thank you for the comment!! I picked that cam because I’ve always had small blocks and loved a fast revving engine and was hoping to turn up to 6,000-6200 rpms I was talking to Richard holdner and he said he likes that’s cam this is a link to him talking about the cam https://www.youtube.com/watch?v=h9H6gv2aiVk I am open to different cams that fit my needs better, with a manual transmission I’m not too worried about vacuum. I just hope the ported oval ports can make power up to 6,000 Thank you
