C7 LT4 cubic inch increase

Has anyone gone bigger on the cubic inches for the LT4? I'd like to go to 427 CI

there's really no point. you'll get more power from pulley changes.

you can if you want, but you will reduce RPM capacity and durability.

I see the big HP guys use a specially prepared 416 CI Block. I'm an old gear head on my second Corvette. My first Z06 had the MAGIC NUMBER 427 LS7. I was just wondering why not 427 CI for my car? I like the Calloway 757 HP because it doesn't blow up the factory warranty and is mostly a bigger supercharger. Nice looking installation and torque increase. It would be killer to me combined with 427 CIs.
