Used 216 / 235 Value
These are worth about $150 +/- fan to clutch *if* they're in running order .
It takes time to sell these so if you're building a Hot Rod , don't give up as sooner or later I'll send someone to you who'll buy it .
Many '31s were upgraded to 125's in the 1960's when they were plentiful so be sure to clean and copy the serial numbers on the smooth flat pad near the distributor , then post them here or go to The Inliner's Site where they'll have de coding info .
One the one hand , I'd think an original 1931 Chevrolet engone to have good Dollar value but , it isn't always so ~ my buddy had a '32 Plymouth engine , tranny , rear end , 5 wheels & hub caps etc. all in very good shape and low miles, he waited three years for the $150 or _any_ cash offer before loading it into the scrap tailer......
