The MSD rev limiters are not too dear and are quite effective in forestalling engine destruction a result of attempting to push my right foot to the front bumper with the accelerator pedal firmly underneath. I ran the old 350 up to 7k+ without the rev limiter before and paid the price. These should keep me in check.
