How fast can you run a g705 engine with stiffer valve springs but not a balanced motor?

For pulling, I wouldn't be afraid of 3000 rpm. For field work, I wouldn't go much over stock.

If its a diesel the limiting factor will be pump timing, unless you go to a newer pump with timing advance.

Mine is totally stock I I run it 2300 rpm. He's right that timing becomes tricky since the indirect injection is a slow process. At higher rpm it sounds like it needs more timing but as the rpm comes down it falls into its power band and pulls like crazy LOL. The good news is that with the Roosa-Master pump you can quickly and easily adjust your injection timing to find your "sweet spot".
