"Great upgrade, straight forward install, great product"
"Fit perfect. Came with everything you need including an ignition cover gasket not pictured. Jk it don’t come with a new crush gaskets for the exhaust nor the oil line. The cylinder is stamped BBR. I used it with BBR cam, rev box, and exhaust. The power felt like double the stock however it don’t feel too fast like your loosing the playfulness."
