We bought one of the trannies from Eddie and Bill some time ago and are just now getting around to posting the results. The car: 2007 SRT8 Charger The mods: 426 stroker with heads/cam and an HTV2300 blower The power: 600rwhp/650rwtq The verdict: Spinning the tires at 75mph on the interstate no problem. Barking every single gear including the 3-4 gear change which is well above 120mph. This transmission is the real deal and the customer is absolutely loving every second of it. Awesome job Eddie and Bill.
