Martin.....do you think that an Arrow crankshaft 84 mm, with alluminum alloy block 91 mm (+ 10 mm deck height) and Arrow con rods 133 mm for stroker kit, is always better?!

Or, for example, is always better an Arrow crankshaft 88 mm, with alliminum alloy block 91 mm (+ 10 mm deck height) and Arrow con rods 133 mm?!

I'm trying some tests, and an Arrow crankshaft 82 mm, with alluminum alloy block 90.8 mm (+ 10 mm deck height) and Arrow con rods 133 mm for stroker kit...is a great solutions!!!

I want to run very high, above 8000rpm lol!
The head is a touring-car spec, with BD16, double valve spring isky, big valves (+1 mm), and full ported/machined head....8500 rpm and above ya!
