You would spend about the same building an engine like that. Don’t forget Titanium rods and valves are not cheap parts.
That is true, but at that point, the engine would be able to handle more stress and more boost. Building motors such as this is not cheap
The LS7 isn’t designed as a boosted engine so I don’t see your point here. There are people making over 600 rwhp with just a camshaft and bolt ons on these engines which is very impressive. Not many people have a 600+ rwhp car without forced induction
The original post mentioned SC the engine…but just boltons would work just fine, but the engine is not capable of supporting boost in its original configuration.
