Hey r3v, I got this as a partial trade and have decided against using it to build an S52 off of, I'd rather just save up for a whole thing and I may go the aluminum M5x or S50 route anyway. The motor, to my knowledge, had 146k on it before being pulled and used for parts by the PO. It has the rods, crank, block, everything a bottom end should have but I will NOT part it out, selling as a whole. I'd prefer local pick up because this thing is damn heavy and damn greasy. Asking $550 as is, located in Salinas CA, willing to meet half way for reasonable distances. Pics will be up tomorrow AM, please PM me for specific requests or any other questions, thanks r3v!
