it wasn't bd but i put the 4.3 in a 4x4 for a guy about 6 months ago & he had a bolt on kit for it. i noticed that a 350 would take a lot more fab work than he was willing to pay for (firewall, fenders, etc). plus it was pretty spendy for the remote mounted water pump & serpentine belt kit because it was just too damn long (unless you reworked the firewall)
i'm not saying it's impossible, just a well built carbbed 4.3 is almost as good & 1/4 the work.
i'll try to ask him how much it was & where he got it. it had EVERYTHING!! radiator, tranny x member adapter, motor mount adapters, power steering bracket & lines, i mean EVERYTHING.
good luck...
