Be aware that you will probably have to run more fuel and less timing to the rear cylinders because of the way the air flows around that elbow. I have something similar on my 10.5 car but it comes in from the rear and the front cylinders get all the air. Its not a problem just pull all the plugs and compare after some WOT pulls. I had to adjust something around 15% on my car from front to rear.

After I said this I wasn't sure the stock OS allowed this. I have Big Stuff on my racecar and it does. However I just looked and HP Tuners does allow a Static retard vs Cylinder and an Injector Gain vs cylinder. I have never used this with HP tuners and there is a warning that some operating systems can cause high rpm operational problems when using this.
