buy new or no
But the minute you start modding it with a big cam, the clock is ticking.
Lots of LS1's dont make 100k after having a bigger cam installed and then again there are those who dont break anything so it really is just a guess. My broke with 84k and a tr224 cam. Which is a small cam by todays oversized standards.
A forged bottom end is a good way to go if your going to be abusing the engine but if you just looking for a few extra ponies a small cam and maybe some lt's and you should be good to go for a while. Start living in the 6000-7000 rpm range and your changing your life expectancy of the engine.
is it cheaper to just buy a shortblock or have ur blocked forged?..........my plans are too buy a 1st gen later on and throw my existing motor into that and get a short block 427 for mine......dreams dreams for now......
