I bought the 625cc big block for my EzGo. My cart is lifted 4" as I use my cart on a small ranch. The under carnage that came with the kit hung very low so I modified it and raised it up about 3". I remade the exhaust to exit out the rear and used a different muffler for a better fit and look. I made a flatbed for my cart previously as it is a work vehicle. I am happy with the kit even though I made some drastic mads but it sits in my cart very nicely and looks very professional. ( I build street rods for a living). I am in the process of wiring it and then I will build a front grill guard, paint the body after some mads and add taller wheels and tires. It is an easy project and you have the opportunity to modify installation to suit your needs. I have not started the motor yet but I am happy with the install kit that Vegas Carts put together. Looking forward to a long life with my new improved cart.
