Do any of you guys Know where I can find this engine for a good price? I've seen it advertised for as low as $120usd. Also, do you guys know of a good after market cooling head that would fit it's 4 bolt pattern, all I've found has been Crazy Nut Racing's, but it costs $69. Also, does any body have an engine tuner to recomend me to? I plan on sending my new Hyper 8 port to Smeltz Racing for a complete modification job for $100. Thanks!
