I'm 16 years old and I'm getting ready to build a 89 GT. For an engine I currently have a 351w that's bored .30" over. I have been doing alot of research and stumbled upon the 427 stroker. The kit is on Ebay for about $700, it comes with pistons, connecting rods and a crank. I also plan on putting a little bit of nitrous on it. My goal is around 10.5 seconds, but low 11's would work. If it pulls the wheels that would to. The car has the 3:73 Posi. I was wondering if anyone has any experience with the 427w. According the dyno sheets it should be around 550hp on motor. If you have any advice I would love to hear from you. I'm young and need all the help I can get. Thanks
