DIY Engine Build questions

Generally, I know IAG has short blocks, but for 4800 for just a short block it's out of my price range for right now... (student loans and only just starting my career) I know with what parts I already have, and what I'd need to buy to rebuild this engine I'd be well below that. There's a local race shop that can do the machine work, for less than $500 (block, bore and hone, then clean the heads).

I might look at just bore and honing the block, putting in better internals and just refreshing the heads... and then redo them later on. For now, I just want an engine that can comfortably push 350-400, and maybe have a map I can run ~450hp for my last 2 runs. Our autocross courses usually see 70+mph at 1-1.5mi long.

Even stock, it is not uncommon for the cases to be out. NA, I was planning on line boring if I was to build.

pick up a 3.7 or 3.9 FD that is what I'm doing. You are going to need a lot to hold that power

I've heard of this but it's beyond what I know currently...
Is this something you can check on your own or does it require advanced machinery?

Is there an amount that is tolerable if you're still running the engine to only 7400-7500RPM? I know physically more power/RPM will make it considerably worse, but I'm on a factory block now that's been running ~350wheel for 2 years ~40k mi ( at that power level)
