High revving 340 stroker questions

I have an inquiry in with an engine builder. We’re meeting next weekend to talk about options but I’m being inpatient so I figured I’d ask a few questions on here.

I’m interested in building a 340 stroker. If like to run low 10s on motor but also be capable to run a moderate sized shot of nitrous for grudge type events.

my builder mentioned that he likes to build higher revving engines with shorter ish stroke cranks.

does anyone have any experience with the higher revving small blocks and why he would recommend that?
