I've spun 428s past 6,000 lots of times, and I wasn't worried about blowing them up. They didn't feel lazy either - even with stock/heavy pistons In fact, they revved faster than many of the 302s that I've had in the past.

That's with a 3.98 stroke vs. 3.00 for the 302.

I just bought a 4.25" for my 427, because it was easier to get a decent compression ratio with flat top pistons. I was going to buy a stock 3.78" stroke because I don't need more HP in a Cobra. It's a custom order, though, and as mentioned, I'd have to run pop-up pistons to get over 10:1 CR.

We each buy parts for different reasons. But it does get old hearing the myth that strokers don't rev.

Btw, I also have a 4" crank in a 351C. I'm more worried about the stock block than I am that it won't rev.
