So I've heard several people say the Grubee kit is good. But today I came across a kit on ebay by "Lucky Early Bird" that looks nice, It has an angled spark plug for better ignition. It looks like it might be the same kit that "Boy Go Fast" sells. I feel like if I get the Grubee it will be one of those "I should've got a Hemi" situations, but I don't want to get something that's going to break after 100 miles.
