Well if you are planning on running a big shot, I would recomend a progressive controller. Having all 250 hit on the street will net you in loosing serious traction, progressive controller will help with the spray to come on alittle easier and not all at once. Make sure you block, pistons is ready for that hit. Blower/ Turbos are cool to if you can afford the kit. I have alot of money in the motor and wasnt able to afford a blower like I wanted. So I just raised the compression on my motor, 12:1, now my cam is to small and is robbing of alot of power that this motor is capable of. So its all up to you on what to do, I personally like spray.
