If the truck was running prior to changing the plugs and rotor, there's not much that could have gone wrong. You didn't mention changing the distributor cap. That usually goes hand in hand with changing the rotor. Make sure the rotor wasn't installed 180 degrees off. Double check the spark plug wires to make sure they are on the right plug. If that all checks out, then you need to pull a spark plug and check for spark and fuel at the cylinder.

1-8-4-3-6-5-7-2 SHOULD ALSO BE ON THE TOP OF THE FACTORY INTAKE MANIFOLD

They are cetainly different so NO they do not interchange

if u are changing spark plugs do one at a time is the best way,,if u need to know witch plug is # 1,,drivers side,, looking at motor from fender,,first left plug is $ 1 next # 3 next # 5 next # 7 is the last plug yo the right,,passenger side,,looking at motor from passenger side fender,,first plug to the right is # 2 next # 4 next # 6 next # 8 should be the last one on the left,,this is going from front of motor to back,,if u need firing order its ,, 1 8 4 3 6 5 7 2 ,, hope it helps

the gas tranny should work. gm was pretty good about keeping the same bolt pattern.

The engine will bolt up with little trouble, however the rest will be a problem. Depending on the engine you will need to bypass the transfer pump and switch soleniod if it has duel tanks. Also the transmission should have a least a lockup torque converter that will require a PCM to operate. If you going this route and live in a any that is not subject to emissions inspection I would recommend replacing both engine and transmission, also the 5.7 will problable to supply sufficent torque for a truck of this size. A better fit would be a 7.4 liter and a 4L80 trans. Either way it will be a rather expensive conversion that will result in lower fuel economy.

Hi, I have pasted the procedure below. Your spec is 0 degrees (right at TDC).

CHECKING AND ADJUSTMENT

HEI Systems

1. Start the engine and allow it to reach operating temperature. Stop the engine and connect the timing light to the No. 1 (left front) spark plug wire, at the plug or at the distributor cap. You can also use the No. 6 wire, if it is more convenient. Numbering is illustrated in this section.

Do not pierce the plug wire insulation with HEI; it will cause a miss. The best method is an inductive pickup timing light.

1. Clean off the timing marks and mark the pulley or damper notch and timing scale with white chalk.
2. Disconnect and plug the vacuum line at the distributor on models with a carburetor. This is done to prevent any distributor vacuum advance. On fuel injected models, disengage the timing connector which comes out of the harness conduit next to the distributor, this will put the system in the bypass mode. Check the underhood emission sticker for any other hoses or wires which may need to be disconnected.
3. Start the engine and adjust the idle speed to that specified on the Underhood Emissions label. With automatic transmission, set the specified idle speed in Park. It will be too high, since it is normally (in most cases) adjusted in Drive. You can disconnect the idle solenoid, if any, to get the speed down. Otherwise, adjust the idle speed screw.

The tachometer connects to the TACH terminal on the distributor and to a ground on models with a carburetor. On models with fuel injection, the tachometer connects to the TACH terminal on the ignition coil. Some tachometers must connect to the TACH terminal and to the positive battery terminal. Some tachometers won't work with HEI.


WARNING Never ground the HEI TACH terminal; serious system damage will result.

1. Aim the timing light at the pointer marks. Be careful not to touch the fan, because it may appear to be standing still. If the pulley or damper notch isn't aligned with the proper timing mark (see the Underhood Emissions label), the timing will have to be adjusted.

TDC or Top Dead Center corresponds to 0°B, or BTDC, or Before Top Dead Center may be shown as BEFORE. A, or ATDC, or After Top Dead Center may be shown as AFTER.

1. Loosen the distributor base clamp locknut. You can buy trick wrenches which make this task a lot easier.
2. Turn the distributor slowly to adjust the timing, holding it by the body and not the cap. Turn the distributor in the direction of rotor rotation to ******, and against the direction of rotation to advance.
3. Tighten the locknut. Check the timing again, in case the distributor moved slightly as you tightened it.
4. Reinstall the distributor vacuum line or the timing connector. Correct the idle speed.
5. Stop the engine and disconnect the timing light.

Check the big plug behind the dash - they can come loose

Dealer check codes

try cleaning battery connections and starter connections if this was helpfull please leave good feed back

with truck off, move passenger to full hot and driver's to full cold. turn key on and run air for 15 seconds.

turn key off

move climate controls to opposite positions and turn key on again with air on. Run for 15 seconds. turn key off.

center temp controls and turn key on again. this should fix you.
move

Who told you to floor it to start? Not even a carbie one start like that. Just crank it and it will start otherwise you floor the engine with too much fuel it wont start.

When you say no power, do you mean no headlights or anything ? Do you have power at the starter posts ?
