You may have to contact NHRA tech dept. Even combo's that have been running and setting records for years, do not have the port volumes listed in the engine blueprint guide. Dwight does a fantastic job, but is still at the mercy of what information is available. Once the info is pulled by NHRA tech, it is updated quickly. If you email Danny he will get you the needed information quickly and also send you the information.
