The differential is going to be a limited slip Getrag unit that I pulled from a 2010 Challenger SRT8 I parted out. The Challengers with the 6 speed manual transmission received a 3.91 ratio vs the 3.06 that came with the automatic. My 2010 Challenger daily driver has the exact same 6.1L, 6 speed, and Getrag 3.91. With the .50 overdrive ratio, I am turning 2,000 RPM at 85mph. Should be fun off the line and still comfortable on the highway. The differential just got installed so that exhaust could be routed.

The OEM SRT wheels just didn't look right so I finally decided on a wheel.....now that I know the 20x9 will fit over the Brembo calipers, I can order up the other 3 wheels.

Front tires are 245/40/20 and the rears are 315/40/20. I've got room for more tire on the rear, but I'm happy with the 315 size and price. Since 315/40/20's come on several production vehicles, prices are much cheaper compared to a 325 or 335.



And a few pics of the wheels on the car...

I bought a fuel tank (for fuel injection) from Tanks Inc. but the independent rear suspension frame is so huge that a stock fuel tank won't fit. So....the new tank had to be modified. Here's what it looked like in stock form:



And modified....

Thanks Pat!

This 6.1L came out of a 53K mile 2009 Dodge Challenger SRT8 that I parted out about 18 months ago. It ran great when I removed it, but I want a little more then the stock 425hp. I pulled the stock heads for inspection. The cylinder walls and pistons are in good condition.

I have a set of CNC ported 6.1L heads that came off a car I parted out about 4 years ago. I had then cleaned up and inspected by my machine shop. They did a valve job and installed new valve seals.
While the heads were off, I removed the lifters and installed an Arrington SR2B camshaft. With a good tune, the CNC ported heads and cam should be good for close to 500hp

I had a few changes made. I was not happy with the fit of the passenger side door. It must have been tweaked because it never fit right. So I ordered a new AMD door shell, but the quarter panel was installed using the original door so the leading edge of the quarter panel had to be sliced and worked to match the profile of the new AMD door.

Both front fenders had to be tweaked to fit the big tires and the low stance. The brace that runs from the top of the arch (up over the tire) had to be reshaped. Also, the front corner of the arch was modified. The corner was sliced and moved forward.

I also didn't like the driver's side front fender. It had a pinhole that turned into more then we planned on. Plus I had a brand new AMD fender that I had picked up for pretty cheap so it was installed.

I picked the car up yesterday and I'm very happy with what was done. I LOVE the stance! Part of me wants to just get it running and drive it as is!
