Why wouldn't you just build 198/210 then the only advantage I can see building 170/210 is a lighter piston which I can't see being a overly heavy piston in the first place, if you want a revver just build the 170.
Because there is still something to be said about having larger cubic inch displacement. Not that I want to hijack the thread, but for me personally I have a want to have something different than the rest. Not just follow the crowd cause its the easy thing to do. If I had not worked in the machine shop where my 225 was built (by me), I would have had $5k into that motor in parts an labor. An I could have built one hell of a V8 for that. But yet still don't regret it, the engine was sweet.
That may be a driving force for the OP. To have something that doesn't follow the crowd, but will draw a crowd. Don't know for sure.
