Crowers are nice pieces for sure, best out there my opinion, but overkill on a street motor.
When I mentioned "aren't that expensive" I was referring to one of several other brands. You can do a forged full floating I-beam with cap screws for under $300 from several brands like Eagle, Scat, Manley etc....and there is absolutely nothing wrong with these.
You'll be into rebuilding stock rods for more than half that which is why the aftermarket option makes sense. Stronger, lighter etc... for very little extra money.
