Last week they were on sale for 259, also at the home depot online site. Yes they still are on sale at HD online. That is the 420 in my cart, I did both a stock one and hopped up one. The stock one has a lot of power, certainly more than stock. Its got 5-6 years on it and still going strong with daily use in the summer. I did another in 2012 and just took that one out and putting a cam and rod in it now. Dang I have two G9 engines that ran fine just smoked, I should dig them out and sell them or the parts lol! Don't think I will use them again, I was going to rebuild one and find a cart with a bad motor to put it in, but if I did I would put a 460 in it and keep it lol.
