well my tires where rated for 400 miles an hour , and my cage and safety gear , fire system will be way better than needed for my 200 mph pass , weight is an issue , but it's safety first ! as a young man i ran my 37 dodge p/u up to 160 mph on the freeway , it cuts the air very well going forward , side profile is a bit flatter and a side wind cause be trouble some . the body must stay of stock configuration , so the windshield angle is the only thing that will slow the air from traveling over the body cab . a cooler tank and fuel tank in the bed and the radiator in the bed as well will be there for added traction , the inner coolers with replace the radiator up front , and that all iron motor up front should keep it on the ground
