Question, apart from the base gasket reasons, should I go for short 117
or long 119.5mm rods, and if so, why, after all, would it really matter with a supercharged motor ?

I might bring it down to a 70mm stroke for 1515cc

119.5 / 117 = 2.14% longer.

a always go for the longer rods and spacer plate as needed, rod ratios are better
one of the hillclimb car guys i know building 1600cc+ stroker motors has a special order rod from carrillo that is longer again , says the bearings are lasting much better

Thanks Maj. Will probably go with the 119.5s.

I wonder if what should be lighter Titanium Crower Rods would improve bearing life ?
As the motor would be supercharged, do you think I'd be better off with Titanium Gen2 Valves or Stainless, and what would be best valve springs ?

Changed me mind.
Lightened & balanced Gen2 OEM 65mm crank with offset journals, & will just use another 86mm bore offset block & 86mm Ross Turbo Pistons for 1510cc. Will just have to use 12mm Cyl Studs to make up for not much space between cyl bore n boost pressure.
Crank Bearings should last forever. Any reason why an Offset OEM Crank wouldn't be possible ? I'm not too knowledgeable in crank building, but any welding involved in having offset journals like there is in stroking an OEM crank ???
