400/426 Stroker. Ever heard of one?

Not necessarily after fit. The lighter weight is a plus but, I’m mainly after engine characteristics. I LOVE the free spinning nature of the 340. I’m hoping to achieve the same characteristics with extra cubes for a bigger punch

You’ll get the 340 feel for sure. It’ll be very similar since it’s a big bore short stroke deal. Just 86 inches greater.

DV did a few small block chev rod lengths shootout each made little more hp than the last I think it was 7-10 hp from shortest to longest if I remember right. I like the idea of ideal bore rod and stroke ratios but wouldn't say necessarily needed for most there's a lot of low hanging fruit to go for 1st to make easier power.

Long rod more HP?

Years ago 20 to 30 years ago, there were some racers out in the west coast area who did a ton of experimentation with off set grinding B and RB cranks for big cubic inch engines. I used to know some of their names, but I'll bet most of them have gone to the great race track in the sky. The reason I say they maybe gone is, I was in my 30s to 40s at the time and they were at least 10 to 20 years old than I at the time. I'm now 71 and can't recall seeing or hearing from, or about them for years now.

It’s unfortunate when the old timers is pass on. I hope they are in the great race track in the sky. Having fun! The problem is a lot of the little things the experimented on, they probably didn’t even write it down. A lot of the old timers, they did things and kept things in their head.
