i have a 92gt with just over 200,000km (approx. 124,000ml) the original owner was a old lady and she took very good car of the car its in real good shape, now my question is is it worth it to do h/c/i upgrade or will the bottom end be to weak? i dont want to build the top end up if the bottom end will just fail any input would be good. thanks

not that it will fail, your engine may just have more oil leaks. I would think it would be okay myself if compression is good.

depends what your hci combo is

mild stuff should be ok just make sure you torque everything to spec

i spray my car with heads and intake and have 150k on the original bottom end

so your fine... do a compression check for the heck of it.... hopefully all cylinders are similar to each other ... over 125 would be nice.

I sc'ed a Mustang with around 140k miles and never had a single issue, it ran 12.4@112 with a bone stock motor and a Novi 1000. I have seen WAY more issues with rebuilt motors than original shortblocks, I really would not worry about it. Do a leak down test to make sure the rings are still good. A compression test only tells part of the story.
