good online engine source?

[cstanley]

anyone know of one? (besides this board, of course!) like a broken record, i, too am considering the modern 5.3 swap vs. rebuilt 350. while just about everything else on the truck will be restored to factory specs, it will also be my daily driver, and i'll need it to be very reliable. therefore, i'd like to go with the ls1 swap with 700r4 or 4l60. i'd like it to be smooth, quiet, reliable, not obnoxiously loud (like it is now.)

so, does anyone know of a good resource for pulled engine/trans combos? preferably online. i know someone was just selling one on the board, but i'm not quite ready to buy. i will be soon, though. i don't want a gm crate, just a gently used modern motor with overdrive trans and computer. wrecking yards here suck.

thanks!
