We are building a 67 Camaro RS with a Pro Touring vibe. Both Nathan and Skip were extremely helpful and patient in answering all of our questions (and we had many) as well as offering suggestions and input when asked for. There web site is great but their listings on e-bay are so detailed and upfront it is what sold us on their company. They are very honest and upfront and stand by their product 100%. Not only will I buy all the rest of my engines from them for future builds I will most definitely recommend them to anyone looking for any type of engine.
