I ran some 5.40's with a very mild pump gas type big block NA in a tube chassis type car and I know I wouldn't make it anywhere near what these cars are now capable of. To keep up with these boys you better have a big inch engine, big tire car, and with a power adder so you can set the car up to run and HOOK on the street. Anybody with enough money can go fast on a prepped track but on the street you have to be educated on power management or they would school you real quick.
