Most likely and 6-71 or an 8V71 for that year unless it was upgraded later in life. Just gave away an 8V71 out of a 73 Astro hopefully it will do someone some good. 92series had some head problems if I recall. Detroit lost a lot of market share sticking with the 2 cycles when the market was changing. The 60 series made up for the delay though. My personal favorite was a 60 series at 470 hp in a 1998 KW conventional tenspeed with 370 rears . and fumblin are you sure you want georgia overdrive?
