It has works dual rates,+6 round house swinger already. it has the cheapo +2 a arms and such.its pretty much ready to go for a better engine.I like the one in it but the porting on it seems to be for drag racing. Because its pretty mild until you get into high rmps then it flys.ill definitely be getting a promod tranny and I already have a lockup and cover from my other banshee.as it sits how could I lower the compression on it? idk very much about engines but I know a little, not much about banshees becides they haul ass and are expensive
