Rebuild June 07, 2005, 01:54:29 PM I was wondering how much it would cost for a shop to rebuild my 87 v6. I would do it myself (with my dads help, hes done plenty before) but I dont have another engine to put in during, and i need to have it done quicker.I was wondering on average what it would cost, and how long it would take. Im not sure if its even worth it to do it or to buy a whole new engine. Quote Selected
