wrenches with that low of a torque setting. torque wrenches I was too nervous to trust the accuracy of the Ft. The intake manifold typically does not wear out, so clean it and set it. torque wrench even though I have two other Ft. There are two styles of spring seats: the 5.7L is basically flat (with a seal on. If you have some age on your car check the intake manifold bolts, you could be loosing power, or even worse if it gets too loose you could suck something in there you don't want.Ĭaution: Torque when the engine is cold, and absolutely use a known accurate torque wrench, do not do this with a regular ratchet trying to estimate the tightness, if you break off one of these bolts, you are screwed. lbs.ĭo you have to do it like I did, Heck No, Absolutely Not!įor me I just wanted it tightening evenly across the entire intake manifold, and heat cycling at the same time, now I am retired and I have the time to do it that way, you may not. and heat cycled the engine, meaning I drove it and then parked it overnight and allowed it to completely cool down, and then the next morning tightened another 10 in. Timing Chain Cover: Tighten the timing chain cover bolts to 21 ft. Exhaust Manifold: Tighten the exhaust manifolds to 18 ft.-lbs. They create performance gains when the inlet to the manifold is opened up, the runners. Intake manifolds are the final step before the intake charge enters your Cylinder Heads. Intake Manifold: Tighten the intake manifolds to 105 in.-lbs. Open the inlet of your HEMI intake manifold to complement a larger throttle body and smooth out your runners to ensure the best performance possible. lbs., and though you can tighten a few turns at a time following the sequence, until you reach the torque limit. Here are the specs of 5.7 Hemi Intake Manifold Torque as follows: Valve Cover and Oil pan: Tighten the valve cover and the oil pan bolts to 105 in.-lbs. I knew I needed to torque them but I was concerned going straight to 108 in. (EDIT: It has been discovered just through this thread that time wise is irrelevant they will loosen in a very short time period after leaving the factory.) Mine was so loose I have no idea how loose they actually were, in the beginning because I tested their tightness with a 3" ratchet handle wrench, which only allows wrist pressure. If you have some time year wise, on your Challenger you need to check the torque of these intake manifold bolts with engine heat and cold cycling they will loosen up over time. For the heights of all Edelbrock manifolds, please visit the the Manifold Reference Dimensions page.Note: The illustration above is the tightening sequence for the 6.4L intake manifold as it uses the same type ABS plastic manifold, this is not just a 5.7L problem, it also happens to the 6.4L as well. ![]() INSTALLATION NOTE: Port flanges have machined grooves to accept stock port seals. THROTTLE BODY RECOMMENDATIONS: Factory OEM or aftermarket! Not to mention a great upgrade for anyone looking to run a naturally aspirated motor. This means it is an excellent option for both turbo, and centrifugal supercharged applications. The inlet to the intake manifold has been machined to allow for both the Magneti Marelli / VDO style throttle body, as well as the 92mm Hellcat throttle body bolt.Įdelbrock’s tests have shown that it will gain 25 HP over the stock plastic manifold. One of the first noticeable differences is that the fuel injector bosses have been moved to improve flow, and it has nitrous bosses integrated into the vertical runners of the intake manifold. The Edlebrock Victor II EFI HEMI intake manifold is overall very similar to the stock 6.1L aluminum intake manifold. ![]() carburetors atop an aluminum intake manifold, creating the 340 Six Pack.
