Old horse new beating cam question

Is the owing son's objection tho the spring change due to not wantting ti change much at all, or just the price tag? And, if owning son does not want to have a high maintenance car, that may say....don't mess with it!

If you keep the lift at or below the .450" lift range you can 'get by' with stock springs. Even with stock springs, they will operate up to the RPM where valve float starts, and that is around 4000-5000 RPM. (I see AJ has posted a similar number.) So some benefit will be realized with a cam change, since the intake and carb are being changed to allow the cam to actually increase breathing. If you don't want to soften up the low RPM operation, then you have to stick with a low duration cam, like a Lunati Voodoo 700201700. Those will help in the 2500-4000-ish RPM range. But you need to be careful with break-in procedures and maintaining adequate ZDDP levels in the oil for a fast rate cam like the VooDoo.

Note that the problem with the 'typical' cams is that once you increase the lift, then the duration gets long-ish and that hurts low RPM torque, which makes the engine 'doggy' at the low RPM's. That is the reason to go with a faster ramp cam, like the VooDoo types. BTW, if you do go with the VooDoo type cam, then I would not get their recommended springs. I'd use something less aggressive like stock 340 springs.
