How many cubic inches can I obtain with the 4.8L/5.3L block? I've heard of people taking these blocks all the way up to a 383, but how reliable is that build? I only ask because I am having a lot of trouble locating a 6.0L block here in Florida. I've been away from the forums for a few years now, so I am a bit out dated, hence my asking what could be stupid questions.
