At TIM ZEPP ENGINES for over 17 years we have been involved with the development, building and the dynamometer testing of professional drag race engines. Every single one of our "DRAG RACE SERIES" engines are tested and tuned on our dyno. When you pick up your engine, or your engine is shipped to you, it comes with the specific dyno test sheet from that engine. The engine is complete from carb to pan. We have listed a few proven reliable engine combinations for you to look at. We have many other combinations on file that we could discuss with you. Isn't time you purchased a race ready engine from TIM ZEPP ENGINES for your drag race car?
