SB Road Racing/Nascar/Sprint Car/Reving BUDGET BUILD

"I want to build a budget small block that revs to 7,000 RPM." Someone please tell me what's wrong with that statement......
You're gonna spend real money making a small block valvetrain live reliably at any sustained RPM above 6 grand. Then you need the cylinder heads to support as well. Not doing that with stock castings. You have a gen 3 already, do what Dion suggested and find a stockish 5.7 and get used to the car. Even with just a cam swap, the gen 3 is capable of heavy breathing and some good RPM.
