Definitely wait for something better!!. (only if you want to though) I have seen numerous mid 90's 4.3's complete
for $400.00-$500.00. Usually complete vehicle! That means
trans, diffs, whatever!! But, hey, whatever floats your boat!!
I will have to agree with Kruzrtec, the earlier 4.3's were inherently rough when idleing and didn't have the roller cam and vortec heads. I have owned an '86 and a '97 and the '97 would run circles around the '86, so even if you spend a little more money but a late model.
