It sure is only buy 7strand 550 more expensive but better quality yea that little monster can pull.
@Pfp dad. It must of been fun with the cord ?
If you figure each strand has a breaking strength of 550lbs then factor in friction, extra weight etc. I'm no engineer, but if one is good, two is better and so on and so forth. Use a whole bunch to spread the weight and it'll pull pretty much anything reasonable with a car.
