Is building a stroked 318 better than a stroked 340/360?

I'm happy for people to have religious faith, if that's what they want. But I don't have "faith" in whatever Smokey Yunick and Dyno Don and David Vizard etc etc did back in the day, as it applies to everyday sub 600hp street/strip engines.

I'm not saying there's no relevance in this stuff. Just that it's not relevant to us.

It’s not relevant to you because you dont want it to be. Has nothing to do with faith. It’s called testing. You need to do your own testing, or just keep your opinions to yourself. Your opinion doesn’t line up with actual testing and racing.
