Re: Limits of stock LT5 with boost?
My guess would be that all things being equal, a stock configuration LT5 on boost, the most likely first failure would be head gaskets.
We already know the bottom end is bullet proof as evidenced by the 415 builds out there, and also considering the success proven by FastLane's and Dave's Obsession cars.
Of stock valve train failures there only have been a few that i've heard of over the years, although i have heard of multiple camshaft failures, but those were attributed to aftermarket camshafts made from incorrectly hardened steel.
If i were to guess, I'd guess that big enough turbos could easily drive the HP well in excess of 600-700hp, but the first hiccup of any kind would pop the head gaskets with ease.
Just my $0.02
