5.7 l GMC 1988

If you purchase a re-manufactured engine they come with a warranty, and the engine has ben totally gone threw. As far as time, it is faster and easier to do it this way that to go threw and rebuild the motor that is in there, unless you know somebody with all the proper equipment to do so.

Thank you bro liking to spend about five hundred on tools I have very few any ideas on how I should spend my money

Good morning Trev. tools...I love getting new tools, Sears Craftsman tools are pretty good, life time warranty so when something breaks, just take it back and get a new one. There socket, ratchet kits are nice, you can get like 120 different pieces, metric and standard size for reasonable price, you'll want metric also, wrench set, with metric wrenches also, It is nice getting sets as the tools are all held together in a carrying case, makes it easier to keep track of the tools. A good set of screwdrivers also. From that point, just see what you would want or need for special tools while doing the job. I don't know what your plans are for pulling the engine, like you would probably want to rent or find a cherry picker if your doing the work, no sense in buying one, lots of specialty tools you can rent.
