I felt it necessary to post this after seeing some of our customers issues with the 3.4L Kit and it's fitment. This is to help them as well as anyone else out there interested in a 3.4L Kit. This will be not only a disclosure to all but also an interaction between other 3.4L owners and their experience with the blower.
So please help us build this thread up by posting information that you feel is important for others to know about the 3.4L Kit.
1. The 3.4L Kit will require you to clearance the center support on the underside of the hood regardless of what type of K-Member you are using. Below is a picture showing where the modification needs to take place for the blower to fit properly under the stock hood.
2. The 3.5" upper pulley has no clearance issues at all with the stock hood. Whipple has confirmed that a 3.75" pulley did fit under the stock hood however the pulley has no lip on it. We will be trying to verify if the 3.80" ones we had made for us will clear as well however until that is confirmed to be safe lets just assume it doesn't. This also means that the 4.00" upper will not clear a stock hood.
3. Lowering the engine with motor mounts for more clearance can be done however you do end up bringing the oil pan closer to the steering rack. We're not sure if using offset steering rack bushings will clearance the rack from the pan but I would definitely like to know. Then comes the question about which motor mounts to use. I spoke with BMR and a few other suspension guru's today and they were all unsure about which motor mount actually lowers the motor as most of them are just made with better poly material but keep the stock engine height.
4. There may be the solution of spacing the K-member. I spoke to Al Papitto today and he turned me onto a guy he knows who makes these spacers. They will space the Kmember from the frame by 3/8" to 1/2" which should help those to run up to the 4.00" upper on a stock hood. I'll be gather more information about pricing and availability on them tomorrow.
5. The 3.4L will require the use of aftermarket fuel rails. We already have confirmed the CPR rails do fit without any issues.
