Former ASE master retired since 2003. Haven't wrenched on a major project like this in years. Would like to help out a good friend who has 1989 Chevy S10 4x4 4.3-liter v6. The vehicles body frame and drive train are in good shape, but the engine is blown. Found a Mitchell rebuilt long block that has been sitting in the machine shop of a local auto parts store for several years w/matching vin and was able to purchase it for a song... I need to get some type of idea on the flat rate for R&Ring the engine and long block before I get in over my head. Any help would be greatly appreciated.

  • I feel your pain ... just started a new project with my son to do an S10 LS engine swap ... I say "with", but I'll end up doing 85% of the work, lol. Commented Apr 27, 2022 at 11:46

R&R flat rate time is 13.1 hours. With AC add .4 hours. With power steering add .5 hours. With automatic transmission add .2 hours. Source is Repair-Source.

  • Under the "Tags" tab (left hand nav), select "book-hours" and go from there. Or just follow the book-hours link. Commented Apr 27, 2022 at 16:12
