[updated:LAST EDITED ON Jan-04-05 AT 08:33 AM (CST)]I have the original 250 that I pulled out of a '70 C10 around 8 years ago. It has around 72,000 miles, but used quite a bit of oil. It is complete less the carb, dizzy and water pump, and has an extra manifold set. I'm not sure if it is siezed up or not, but I think the price is right. If you need it, come and get it. Free (or would trade for 54-up 235 parts you don't need). E-mail me and let me know. To go along with it, I have a pair of tube headers, but I will need $50 for them. I'm located near Rolla, MO. timkean@fidmail.com Thanks!!
