You are going to step up the most radical change is the Head makes HP not the bore. So, technically you are going to pound the rods with 133K worth of wear on the caps is now cam that up too? Wear out my line bore is the cam is gonna rock in those worn out bearings. How does that cylinder wall look all scored and yes, you leak-down the puppy.
Say you won't see it, but 1 to 2% is race ready or bone stock new. You see 8 to 12% leak is she is dead and tired says, rebuild me.
I would use the same engine that is in it, and if you want to go faster, do not use the brakes that soon... I'm gonna get you in the corner is out brake you is did you have the HP to do what with it? You are going to hammer the pedal and the bottom end is going to sing the blues... Nice try @ 133K worth is even if you kept the oil clean, she is still a worn out puppy is like; install a new dick is your heart is not going to be able to take it, say....
