Needing a good recipe for Pontiac 400 pre 75 yr modle

[Rocky66]

Hi All, I'm needing some good recipes to building a low budget build for a Pontiac 400 pre 75 year. This build has to be done the old school way using factory cast iron parts such as block, heads, intake etc. This build needs to produce 450+ HP. The block can be bored .30 over. Any info on achieving this goal would be greatly appreciated. This beast will be going in my 67 C10 shorted with a TH350 built. Please help me prove to these younger generation of kids who says it's not possible. I'm old school all the way. Age 60. Thanks guy's
