I have a dead 1964 292 and a (?) good 1977 292 , I want to place this engine in my 1969 C/10 with 350TH tranny as the current 250 burns oil like crazy .
The '64 292 and the 250 have the same size / thread bolts holding the flex plate to the crank , the '77 292 had larger bolts .
What now ? .

See this web page:
http://www.rebuiltautoengines.com/chevy-L6_4.8_292-engines.html#EngineTitle1963Looks like early engines were 7/16" flywheel bolts.
I have a 1964 292 that uses 7/16" bolts.
You can use the newer engine if you drill the older flexplate holes for 1/2" bolts. ( I believe 17/32" is what I used)
Of course you need to use proper starter to match flywheel / flexplate diameter.
Good luck.
