426 stroker with 4.5L Whipple Build

Ready to do a build on my Hellcat. I want something somewhat reliable with a fairly conservative tune. I know these builds can push 1200whp with general supporting mods on E85. I’m talking standard 93 octane, conservative build with around 1000whp. I’m open to keeping the stock 6.2 but I’ve heard the stroker is a better option for what I’m looking for. Not going to be racing the car much, but putting many miles on it. Does anyone know the reliability of a build like this?
