6 bolt blocks bore vs boost
6 bolt blocks bore vs boost Thinking of going lsx short block or DART SHPLSNEXT short block. What is everyone's option on how big of bore is too big for boost. Looking at making 1200 to 1500 whp twin turbo.

At that power forget the NA desire for largest bore possible. You need strength and stability. Boost adjustments will make more power than bore and stroke tweaks.
As above - stay small as you can and do not go too large on stroke either - it'll make power but becomes a unit trying to fight itself with poor rod/stroke ratios etc. Keep it simple - build a modest cubic inch size that is super strong and can handle the boost, then you'll have a weapon you can lean on.
I'd love a 441, but if I wanted 1500rwhp I'd stick between 376 and 427 tops. The harder and longer I would be leaning on it - the smaller I'd go. Plenty of all sizes out there doing it - but basic math/geometry says the more conceravtive sizes will last longer given same quality of build/components
