I have a 250 you can have free. Its been out of its original '70 C10 for about 8 years now, so it may be stuck (I'm not sure). But...the price is right. It is complete minus the carb, dizzy and water pump. I even have a set of tube headers for it, but... Let me know!! \:\)

P.S. I'd be quite happy to trade it for that 235...
