I know i know, been here done that.....
You engine guru's don't want to give away the secrets..
just wanted a few opinions
on specific parts
dart big m ? tall or short deck?
rotating assembly ??
longer rods = better geometry ??
pistons?
Heads ?
cubic inches 540, 565, 572 ???
remembering i'm looking for mild bullet proof engines

See this thread- notably Kaama's results:

I would go tall deck if you dont have stuff you need to re-use. Most parts cost the same either way, and in theory there are some slight performance advantages- also wear advantages. Less side thrust on the piston may result in better ring sealing, and piston skirt wear.
