hey guys,
i have a 1999 NBS silverado it the 5.3, ive got 105,000 miles and want to drop a new engine in it..
i have narrowed it down to the LS6, LS2 or the LQ4 6.0...can i just plug and play with all these motors??
whats a good tranny company because i figured i would just replace the tranny b/c i also want to do a STS to whichever motor i install....

What do you guys think....any advice would help.....


thanks,
justin
