Blueprint specifications contain information vital to building NHRA legal Stock and Super Stock engines. Critical dimensions, as well as casting numbers for cylinder heads, intake manifolds, etc., that are verified during teardown inspection, are contained in the Blueprint Specifications.
Engines are listed by manufacturer and year, and identified by cubic inch displacement and original, advertised horsepower. If you do not find a particular engine listed, it means specifications for that engine were never received from the OEM, and the engine is not eligible for competition in Stock and Super Stock.
