    Rated 5 out of 5 by from Truck runs like new......finally! Got this in 2 days from Jeg's but I live about 2 hours from their warehouse. Engine runs smooth and should last 20 years like the original. I'll settle for ten. Had trouble with the Jeg's brand distributor that I ordered with the engine, Part #555-40006, see my review there. Jeg's is great and no complaints other than that darn distributor.

    How much hp can a guy add to this engine?  

    Asked by: 97mustang
    It depends on what you add to it, it can make 300 hp without updating the major components.
