Otherwise there are two 76 takeouts out there at $4500, and a 75 at $5k. Then there's a Farmers built RS spec engine on carbs for $10k.
There are two cases for between $1500-2500 and several cranks in the $800-1000 range.
Puma, those are time certs. The buyer of your engine may be able to avoid sending the case off to Ollies for $3k of machine work. Cases that have been to Ollies and are ready to build are generally being offered in the $4500-6000 range.
