Re: 7100 RPM too much ?
Think of it like this- 302W is a rather short stroke motor. Shorter stroke= higher allowable revs. I think your stroke is 3in, (about 76mm) where ford mondeo V6 has 79mm (and shared with jaguar AJv6 and astonn martin V12) and they can go as high as 7400 in the aston V12, 7000 in the Jag motor and i'm not sure in the mondeo.
The big thing is how long it stays at those revs. Being a burn out car I'd imagine it would be up there often and for a lengthy time. While i have no experience with windsors (or any motor really) I'd be leaning towards strengtherning the bottom end.
It's all about fatigue- and the life of the fatigued component goes down exponentially when revs go up.
Eg- doubling of strain in a piece of steel can reduce it's life from 5,000,000 cycles to 20,000 cycles before failure. PM if you want more info.
