The FI version has a blind hole near intake 3 for the temp sensor II. If you use this head as part of your engine project you don’t have to worry about the hole because it’s blind. If you have the head from the 74 bus, then you’ll notice two holes on either side of the intakes. These are not breather openings to vent pressure from behind the valve cover. They are air injection holes to allow oxygen to be introduced into the exhaust stream to help burn unburned mixture after burning. Two tubes were hooked up to those ports which lead to an air pump that way driven off the pulley. Removing the air pump is a good ideal because it’s overly complicated and not very effective. Some people rebuild their engine using these heads and have no idea why there is soot in the engine compartment or why it’s so noisy. The holes have to be plugged up after the pump is removed. Two tubes are screwed into the holes and they are difficult to remove sometimes without stripping the threads.

Special features on this crate engine include these new parts and more: Be sure to scroll down the page to see a more detailed listing. This engine has the First Generation Vortec Heads. See below for more details! Has EGR hook up for emission, Recommend modified chip note:
The following terms and their definitions are related to both OBD1 and OBD2 systems.
View Photo Gallery Start with a cold engine and disconnect the battery negative lead. Remove the mass air sensor and air-inlet tube between the throttle body and air cleaner by loosening the worm-gear clamps at each end. Remove the throttle cable from under the throttle-body. The cable snaps onto a ball mount, and it can be carefully pried off with a wide-blade screwdriver. Remove the connections for the throttle position sensor TPS and idle solenoid.
The plastic connectors snap apart and will plug back in later. A new one is included and mounted on the new throttle body. Loosen the hose clamps that hold the two coolant hoses to the EGR plate and remove them. Here, the PCV hose has already been removed. Loosen the four nuts that hold the throttle body and EGR plate to the intake. Remove the bracket that holds the throttle cable and TPS plug in place.
Why would changing from v6 to v8 cause this?
They also look like they will flow a little bit better. Part passenger and driver. Here is a comparison between the cast and tubular style manifolds this one is the driver’s side: Any hardware store will have them. With the cast manifolds, one bolt goes through a thicker section of the casting and therefore needs a longer bolt. I used a 2.
Mar 19, · I assume you are not talking about using either the EGR or A/C pins to be able to log the signal in your data logs? No, although i have a pro unit, I am wondering if it is possible to wire in the singal wire into an unused port connection.
Here are the steps we took. First we replaced the plugs that were the wrong ones. With the computer conected we monitored the live data and were recordeing most of the misfires in cylinder 6, 4, 2 with an occational misfire on 5. We had no codes recorded in the ECM but the fuel trims were way off. We pulled the thermostat and found ijt rusted in an open position with the car cold.
We replaced it and retested and the fuel trims were right in line to spec. The next change was the distributor which had a worn gear and a cap with corroaded terminals. Again we still had misfires but they were becoming less. We next changed the crankshaft plug. Wires were bare and soaked in oil.

In a squarebore, the bores are closer to the same size, though, in some squarebore carbs, like cfm Holleys, the primaries may be noticeably smaller than the secondaries. However, even then the bores share the same centerline. Many aftermarket intakes, such as mine, and the Edelbrock Performer and RPM, etc, are “dual pattern” intakes the area where the carb bolts on looks like a butterfly. Either a squarebore OR spreadbore can be physically be mounted on them with no adaptors. Carter Thermoquads, Rochester Quadrajets, and Holley ‘s, ‘s, and ‘s are spreadbores.
If the intakes are true squarebore intakes four individual holes or true spreadbore intakes again, four individual holes, though of different size , you cannot really bolt a squarebore carb on a spreadbore intake and vise versa. In the case of putting the squarebore on the spreadbore intake, the primary bores of a spreadbore, though small, are spread further out than the primaries of a squarebore.
The squarebore primaries of the carb would not line up well with the holes in the manifold.

There are three buttons — set, lock, and load depth. There is also a rotary encoder that allows for finite movements of the hitch. Hitch load depth The load depth feature is a useful tool designed to increase performance in tillage applications. Load depth adjustments allow the operator to make adjustments to hitch draft responsiveness.

Early production was a Gen3 engine in the “classic body style truck” Please let me know if PCM does not match the engine exactly. GM used different injector sizes, fuel rail types etc across engine’s and years. It’s important for best performance to know exactly what the engine is.
(this includes EGR, AIR Injection, EVAP System, Rear Oxygen Sensors on +) You may choose to keep EGR but remove the rest. Let me know and I can keep what you want. Typically If you say remove emissions, I remove them all.
Here are the different types of EGR valves, someone correct me but I believe the 4. Description of types There are currently six types of EGR systems in use. Going from the oldest and perhaps the most familiar they are: On GM cars, they are identified by the last letter of the part number stamped on the diaphragm housing on top of the valve. Prior to , they were not identified and can cause some confusion, so be careful when ordering a replacement.
The letter ‘P’ stands for positive backpressure and the letter ‘N’ for negative backpressure. If there is no letter it operates on ported vacuum. The control valve manages the amount of vacuum to the EGR diaphragm chamber by bleeding vacuum to the atmosphere during certain operating conditions. When the control valve receives a backpressure signal from the exhaust through the hollow shaft of EGR valve pintle, pressure on the bottom of the control valve closes it.
When the control valve closes, the full vacuum signal is applied directly to the EGR valve diaphragm which opens the valve and lets the exhaust gas recirculate. Manifold vacuum is also applied to the lower diaphragm through an intake port at the base of the EGR valve.

The first appeared in It is virtually the same as the FWD Buick 3. In , the supercharged version appeared using a M62 blower. The cranks and heads are all the same, except for balancing differences according to my info. In models, the I SC switched to teflon coated roots in the M62 blower increasing efficiency.

Believed by many to be another possible cause for the horsepower bump, these new mufflers were introduced only on Corvette coupes that were fitted with the optional 3. The increased resonance from the mufflers was deemed too loud for the convertible models. Similarly, the taller gearing of the 2. Advances in chassis design included the introduction of larger, 17 x 9. The new rims featured a freshly designed twelve-slot pattern. To further aid in the development of directional control during braking, the brakes were fortified as well.
For , Corvette came standard with larger, two-piston, front calipers. While this design was not changed for , the location of the parking brake lever was moved a bit lower and further back from its original position with the intent of being less intrusive. The 35th Anniversary Corvette Another, less notable change to the interior involved the modification of the interior air extractors within all Corvette coupes. The model represented the 35th Anniversary of the Corvette.
All were white coupes, with white leather interiors and white wheels, and each received special badging. Lastly, the Corvette was the first to include unidirectional wheels. The 35th Anniversary Corvette. For its 35th anniversary, Chevrolet announced that a limited production of 2, Special Anniversary Edition Corvettes would be manufactured.
