race them and shut them the fuck up. when i was still on stock cylinders with no porting i had a guy wanna race me in his newer model z28 camaro. he was runnin his mouth about how fast it was. i dusted his ass for at least 4 or 500 feet. he said he passed me going almost 80 mph. your 4mm cub will flat out waste those rice burners..id put money on it.
