After searching the Web and comparing what is needed to get this motor running, it's the best bang for the buck, plus it has a lot of bang! Since it is dyno tested with common headers and an edelbrock 750 carb, you know those results are attainable. Shipping was super fast! I've got my 383 in my ugly 69 C10 and it just sounds angry. I love it.
