No they didn't

Only engines with 1 pce RMS crank have a weight on the flexplate ,if your engine is one of those all you need is a '87+ flexplate to suit
153 tooth to suit starter with inline bolts
168 tooth to suit starter with offset bolts

If your crank flange looks like below it is a 1 pce RMS engine ; if not is is just a reg 2 pce RMS SBC as used from 1955 - 86
In any case only the correct one will bolts up , they don't interchange

 

telly, welcome aboard thirdgen.org.

I suspect you meant to say in '92 the flexplate was weighted. Your '84 engine would not be.

A flexplate for an '84 C10 305 or 350 will get you at 168-tooth, 2-piece rear main seal piece. Common as dirt. And cheap ($25 at Advance Auto).
