line boring

[nicolas]

just been reading Keiths engine manual on the toilet and i have reread the part about lineboring again and i am still confused about the fact if it is good or not??

case in point i have a AS21 case that has been linebored to 1mm, but do i scrap it or can i still use it? the reason being i payed all the money to have it opened to 90.5mm and fullflowed...

there is a limit to how much line boring can take place, every time you do this you remove material, it has to be weaker than a non line bored case, but my case is line bored to 0.5, full flowed and 94's, no problems because i don't see 8k on the rev counter.
