440 and 727 for sale on marketplace

I never have understood why people say stuff like "bore it to the max". First, it makes them sound very inexperienced and immature, and secondly, as you say, it ruins a good block. Generally speaking, for about every .030" of over bore, you're only adding about 5 cubic inches. So, there's "THAT".
Ok listen here all you lil buddies. Before Everyone gets their feelings hurt... Let me dig deeper into what I'm going for. Lol By bore and stroke it to the max. I was hoping to bore and stroke it to the max that I can.. safely and reliably... sure anyone can "think" they're going to throw a 543 stroker kit into a 440. Kind of like all the big block chevys I've built In the past. I can't tell you how many guys bored 454s .100 over and stroked them to a 505 and even bigger. they blew up and were literally turds at the track. Where the smart people would do a 489 or 496... or even 468 big block chevys and totally blow the doors off most competitors. So that's what I'm going for. Sorry I wasn't clearer on that one. I want to take a 440 to the max I can before it becomes a unreliable pos. No doubt getting a old block I'm going to have to atleast hone it. And do bearings possibly bore it and even more... I'm going to build this car as a drag car. High compression nitrous engine... just that statement alone means new internals and much better heads/Higher compression. My dad and I did toss the hemi idea around but we decided to stick with a 440 build. NOW whomever said you never bore and stroke a engine for cubic inches. Has to be a clinton supporter lol. I get that most people wanting a nice cool running street engine never want to bore it over if they don't have too. But for all the drag racers out there boring and stroking their engines for more performance. I guess they just don't no what they're doing!? ‍♂️
