right now is the gs model with some up grades like headers,cold intake,catback exhaust, short shifter, stage 2 clutch, swaybars, etc. I just want to see how much horse power i can get from the 420a motor eventually i'll chage the head to a gst or maybe a evo8 head because the 420 blocks are really strong and i dont feel like paying thousands for a gst or evo engine. But yea is a gs but its just chilling in my driveway on the lift cause im performing surgery on it trying to get 210whp on it im praying. I'll talk to you guys latta.
