Dont know if anyone has seen this yet, but I was just on Advance Adapters site and they offer Turn KEy VOrtecs like the Ram Jets. They say you only need to hook up 6 wires and has a stand alone comp. system and harness. Prices/specs are as follows: ENGINE H.P TORQUE WEIGHT PRICE 4.8L 300 300 520 lbs. $4690.00 5.3L 310 350 520 lbs. $5005.00 6.0L 340 400 550 lbs. $5525.00 5.7L 390 380 400 lbs. $6255.00 There HP numbers seem to be a little inflated but they seem like good deals!
