i bore it to fit a 83 mm is it possible to have a 450 on my stock sleeve is cast iron slleeves good enough? i am thinking to have 450 on my stock sleeves is it possible?

 

HUH, sure

 

if you tune it rigght you can do more than that on stock sleeves

 

Um...IMO......NO!

 

thats your opinion . it has been done by many. So it is possible

 

Maybe I haven't read enough? Oh wells. Yes then?

 

it is possible. good for about 15-20 hard runs and then crack!! specially if it is already bored out.
