What goodies do I need to build a Fast slant 6

Seems like slants and big money go together.

I'm building a hyper pak clone. I have no idea how fast or powerful it is going to be but I can say I have a ridiculous amount of money into it so far.

Big power expectations and cost effectiveness in one sentence needs a v8.

I'm doing it for nostalgia and a show piece. But I have the block decked, head milled .090. 030. Over pistons. Hyper pak spec cam (i don't remember off the top) headers and a Clifford hyper-pak replica intake.

I'm thinking it should be a lot more than a stock six but probably not 300hp. For the money I could have already built 3 small blocks.

Probably 220-240 HP. Be really fun and different in a A body. That would sling an early A around pretty good.
