I've learned not to argue with anyone on a message forum, it's all a matter of opinion and preference (some experience helps too
)...
I stated 347 for the reasons that have already been addressed (CHP)... however, I've had a bare R302 block that I've been wanting to turn into a 331 high-winder since '99 ($$$). I know about rod-stroke ratios... I run a long rod 306 (5.400" rods, 1.8:1)
All you can do is present your case and support it with facts... without getting ugly
...and let the person decide for themselves, I never woulda thought the 331 would have become the fad the 347 used to be a few years ago. I thought I was really on to something when I planned for the 331, now everyone wants to run one. I personally prefer the 331, but won't argue with the guy who says the 347 is better...
There is, in fact... no replacement for displacement! ...other than power adders
