[QUOTE="HotRodZilla, post: 1337904, member: 13519"] Sure, polish the ports and blueprint the motor. That will take weeks, just because it's a time consuming PITA. For those that may not know what true blueprinting is, it requires plastiguage, patience and access to parts. Put a bearing in, torque the bolts and then pull it apart and measure the clearance. If it's out of spec, replace the bearing and do it again. A good blueprinted engine will spin for 30 seconds plus with just a hand spin. It's cool. Really, one could probably bolt the motor back together and run it just like that, with a few extra horses, simply from the printing; but all that work to run regular fuel and the same compression? For a couple of horses?? Shit, if my fat ass lost 40 lbs, that wold have the same effect. In reality, once the blueprinted motor is back together, it's time to start thinking intake, exhaust, high compression, fuel delivery. ALL the things Ionbeam mentioned on the previous page. That's cool for track days, not so much for 700+ mile days with good fuel economy and hardcore reliability. You outta do it Falsus and let us know how it goes! [/QUOTE]
