If it has been sitting for a while, I would definitely reccomend that you turn it by hand for at least one full revolution. That way you can feel if there is anything in the engine. You don't wanna hit the starter, and have a piston smack and bent a stuck valve or something. If you don't turn it by one of the balancer bolts, like mentioned above, just crawl underneith, pull the inspection cover for the flexplate, and turn it by hand. On a relatively stock engine, it isn't tough to turn. Just use a pair of work gloves, so the teeth don't bite ya, lol
It'll be located between the oil pan, and tranny pan. It is held on with two 7/16s (I think) bolts on the tranny, and two on the engine. Make sure you pull straight down, and try your best no to bend it on the starter. Once thats off, you'll see what we mean by the flexplate. It'll be the part that has the round torque converter bolted to it. You will not need to disconnect the torque converter, or starter. You can turn the engine by hand which-ever direction you want, won't make a difference if you are just giving it a turn to feel if anything is stuck in there. The engine will not start with no carb, and the plugs pulled out
