how many horses?

If it's a 360, the fact he said "forged crank" leads me to think he may not know much about it really. It's best to see it all apart. Bring a friend with the means to measure things, or knows what to look for for tell tale machining marks and stuff. I disassembled 360 with receipts for all the parts and machine owrk I'd think should go int he $2K range. If he has no receipts for the machine work, I operate under the assumption it has none. Because I'm going to have to measure everything and maybe re-do the work. I would be looking around $1000 maybe at that point. Depends on what all the parts are, and if they are in fact new. (again, not having any reciepts)
