whats a better set up for mx 440 or gt thunder stroker

[Hondarider440ex]

I have a 440ex right now with 11:1 piston,sparks x-6 exhaust,41 fcr carb,and a stage 2 hotcam,and i am rebuilding it after the race season is over and wanted to know if i should keep the 440 or go with the gt thunder stroker kit and how would it compare agaist the 450's

The stroker will be faster, and more expensive.

How heavily modified are the 450's?

IDK my 440 is faster than a 465 stroker I raced. Beat him in accel, and top speed.
