Eh.. Spent 10 years in the DSM/Evo Arena.. Now I drive an 11 second scoob..
4g63>ej.. Stronger block, better flowing head, greater VE.. Etc etc etc..
But really who cares?
Either route can net similiar results built properly.. Until you start to cross that 1000 hp threshold.. There are plenty of mid 1k HP 4g63's.. Not so many ej's..
So as long as you arent shooting for 1500 hp.. Again.. Who cares? Pick the vehicle that suits you better.. Personally I love my Suby..
