'''There are numerous sources of information to assist the untrained individual in the rebuilding or repairing of specific components of a vehicle, but there needs to be a place where he/she can learn what to do and what not to do in the modification of their vehicle(s). This article will attempt to fill in the blank spaces in their understanding concerning these modifications. | '''There are numerous sources of information to assist the untrained individual in the rebuilding or repairing of specific components of a vehicle, but there needs to be a place where he/she can learn what to do and what not to do in the modification of their vehicle(s).

Set the valve cover on the head to keep oil from flying everywhere and fire the motor to let it warm up an little. Do final adjustment on the #1 cylinder rockers. (Chevy, back off the rocker 'til it audibly clatters, then tighten it down 3/4 to one full turn). If you want to go ahead and run the valves on the rest of that side of the block, now would be a good time. Replace the valve cover. | Set the valve cover on the head to keep oil from flying everywhere and fire the motor to let it warm up an little. Do final adjustment on the #1 cylinder rockers.

| − | Hook up your timing light to #1. Remove the vacuum advance rubber hose from the vacuum canister at the distributor and plug the end of the hose with a golf tee or other suitable plug. Adjust initial timing at the crank to what you want. Some use the factory setting while others prefer to set it a little more advanced for good throttle response. If using a little more initial advance at the crank, make certain you don't have so much mechanical advance in the distributor that you exceed the total timing specified for the motor. Most small block chevies will run best with around 32-34 degrees with fast-burn heads and 35-36 with conventional heads. Ignition curve kits are available to customize the centrifugal advance curve in order to limit it when using more advance at the crank. | + | Hook up your timing light to #1.

There, you're done. You should feel much better now, knowing that when you time the motor with a light, it's dead nuts on the money. | There, you're done. You should feel much better now, knowing that when you time the motor with a light, it's dead nuts on the money. | ||
