Default rebuilding the engine while it is still in the car

I was just wondering if anyone has experience rebuilding the engine while it is still in the car. I know when you plastigauge the main bearings the crank needs to be supported, but is there anything else I need to worry about?

Or maybe I will just remove the engine from below the car, and slide it out.

I plan on honing the cylinders myself for a nice cross-hatch, but taking the rotating assymbly to a machine shop for inspection, polishing, and balancing.

Any tips from some budget do-it-yourselfers? I have already replaced a rod on this engine, but now I will be replacing everything.

It's a hell of a lot easier to just go ahead and yank the motor. You can get away with reringing the motor with it in the car, but even then it's kind of a pain in the ***. Plain and simple, it's a hell of a lot easier to pull the damn thing out.

Is it easier to rent a hoist and pull from above, or drop it from below and slide it out? Actually, this is what the title to this thread should be.

mostly everyone yanks it out from above, unless you can get the car high enough for you to pull it out from below

Thanks Jason, thats what I wanted, someone who has done it using both methods. I think I will need another floor jack and is an engine stand necessary or could I just rebuild on the floor?

If you have a friend with a lift or if you have a lift then that would be ideal - theres NO RISK of DROPPING the motor or your baby

Get yourself a cheap engine stand for like $50. I can't imagine what a pain it would be rebuilding a motor on the floor. You have to flip it in order to do everything on the block and then it would be resting on the surface that touches the head. Plus it would be moving eveytime you tighten a bolt, etc. Save yourself the hassle and get a stand.

Try to keep the parts clean. Even lint and dust are big no-no's when doing the final assembly of an engine.

It'll be really hard to keep things clean while working in the engine bay. An engine stand helps to keep things clean as well so the engine is rolling around on the dirtiest place in any room...the floor.

Keep the temperature stable at around 70 deg F, the humidity low (if possible), and the room/garage isolated from external airflow. Assembling an engine with the garage door open is a bad practice.

Keep metallic parts constantly oiled (every couple of days) if the build goes stagnant for any extended length of time.
