ls/vtec qustion

i know many people have written about th reliabilty of ls/tec engines. my ls has 120,000 miles. do you guys think it will blow up if i ls/vtec it with out replacing anything in the bottom end. i dont plan on reving past 7000? if not how many miles do u think ill get out of it before somthing goes?

you shouldnt do ls/vtec at all if you don't plan on rebuilding a lot of the motor no matter how many miles you have.
