Digging around the blazer I picked up there is just to many small issues wiring cut and spliced vacuum hoses laying about. A/f in the oil and the list goes on. So if you have a running 4.3 willing to sell local or even semi local I'm in south jersey but I will travel with in reason. Please let me know what you have and what you're asking. My email is fwoodjr@me.com that's the fastest contact though I will continue to check back here regularly. Not interested in any 350s I have enough of them and this is my wifes daily with our kids so I just want reliability. Thank you.
