Bobby you have way more exp them me, and not to go to far off topic, but I see your reference to 30 40k miles, and I guess your talking a wide lobe sep cam and a semi long service life. Far from a race motor.

Using alot of dur 280-s and at 106 we are still pulling after 7k so why not use it if the heads support it, what is wrong with rpm if the heads/setup supports it and many are running there strokers past 7k.

Are you leaning more towards a 30-40k daily driven motor in that thinking vs somthing that gets tore down every couple years or when needed??? Another member here just tore his stroker apart after a year of abuse at 7k plus only to find no issues.

Im asking this trying to learn, not be a smartazz. I just dont understand why I want to shift at 6k when im still making power to 7k as many are doing? Is alot of it for longer life? Im just a bit confused, your talking 30-40k mile build in the race section.
