thinking of possibly picking up another improved stocker this summer. guy has an older indy with a somewhat of a built up motor (600 indy) says the motor in it is about 130hp. but he has a 600 punched out to the 707 that he says makes 170hp at 98-10,000 rpms that i could get. come with pipes and 44mm megatrons. any one have any input on this motor. thanx

isnt 107 a long way out to go on 600 parts? it may be strong but for how long. if the price is great then try it but otherwise I would build my own then you KNOW what you have. I know some guys that have bought other guys troubles and its cheaper to build your own sometimes. just my opinion.
