some people get it. some people dont. i aint gonna continue to fight with ya. i use 283's for a few reasons, one in my expierience's they last a long time 8 years is good for a motor that is being ran to death every weekend, 2, ive gotten the last 4 of them for free! i got 2 from some guy i met on here. one from my friend craig and the one in my nova my dad got it for free from some guy for doing a tow for him. <dad used to run a towing company> so basically free, cheap horsepower IMHO.
