1970 .30 340 for sale

yeah, I still have the 273 in mine but have two complete and ready to go 340's in the garage. I am going to put one in while I rebuild the 273. then figure out what to do with the 340's... You can get oil with zinc in it I have been through the same thing with this one flattening out the cam, learned my lesson...

It seems like a reasonable deal with your motor I'm sure it wont last long.
