Longer conrods

[HedgeyGedgey]

Hi guys, to cut a long story short it's a common thing in the 4g63 evo engines to fit 6mm longer rods with the 6mm shorter pistons from a stroker.I'm having trouble explaining to my dad the advantages, it produces more power and revs out a bit more. Now I know it's to do with the dwell at tdc is changed so you get a cleaner inlet and exhaust stroke, but is there another reason why? He doesn't understand this concept haha. Thanks
