| I am running the stock Ford manifold on my pickup right now. The previous owner included an Edelbrock intake, is there any benefit to installing it on my 460 carbed? |

What do you do with the truck, how much does it weigh? Which manifold do you have? Posted Via AR15.Com Mobile Stock Ford. Just general use. I don't ever plan to tow anything major, namely just a car trailer and maybe a couple quads on occasion. Its gonna be a dd. |

What I am wondering if anything can go wrong with an intake manifold? Say he ran it and cracked it or something but there is no damage to the engine, is that even feasible? From what I can tell it looks never installed, but just want to be careful. cracked what? the intake manifold? seems unlikly to me without something else breaking along with it. but then again other than rebuilding a 302 when i was 13 with my dad, im pretty inexperianced in this sort of thing. im more experianced with the fuel injected inline 4 stuff. |

It will probably be beneficial for you IMO. |

Well, I don't know much about rigs other than basic maintenance and this particular rig was a good deal but needs some work so I should be learning more. I have a master mechanic/fab uncle who wanted a project and he wanted to teach me, which I couldn't refuse. I should find that out soon. It was whatever the stock ford 460 was I will look it up. |
| The new edelbrock is a dual plane, performer. From what I gather anyway. Seems relatively cheap retails for $150 or so and I got it for free so just wondered if it was worth the time or not. I plan to add a better timing chain and from what I gather these have a crooked timing and I want it straight up, in addition to a better distributor. I noted on Rock Auto, they had a set guaranteeing mpg improvements, is that even feasible? I said bs but some people really did see improvements. I don't know too terrible much about engines but I wouldn't figure a new ignition system would do all that much? |

Buzz Killington here, why mess with a 26 year old vehicle that is functioning? You could be uncorking a problem... It was built as a way to learn about stuff. I am going to fix the timing and add a new timing chain, and dizzy anyway. I got the part free so I figured why not, if there was some benefit. |

If it's the performer intake, sure I would put it on. If its a high rise single plane intake, nope don't waste your time and money. Posted Via AR15.Com Mobile |

Does the new intake manifold have one big hole on top, two medium holes or four small holes? One big hole = single plane, you will lose low rpm torque. ETA: I was typing while you were, I see now you say it is a performer, you will probably pick up a few hp over stock, but not enough to change it IMO unless you upgrade the cam and carb as well. |

Your right on the timing, I was told a 429 timing set is what you need to run on a 460. I don't know for sure though, I never done it. Posted Via AR15.Com Mobile Yeah I don't know much about timing either but from what I under stand the timing is off center like 4 degrees, or 15 degrees or something on these models and it needs to be adjusted to 0 with a double roller timing chain. |

From what I can tell it looks never installed, but just want to be careful. I bought an intake once that was improperly milled. Looks like someone took it into a machine shop to have it milled to fit shaved heads and they took off material from only one side. The bitch is that I couldn't tell until it was on the car and wouldn't seat to one of the heads. |

Stock cast manifolds for the most part have less than ideal passages, and when it come to matching the head ports, are even worse.
The passages in the Edelbrock manifold are mush smoother, and depending on the design, will atomize the full much better for the desired RPM range. Now having said it, before just installing the manifold, make sure that it's exit passages match the intake passages on the head and the carb that is going to be used. A mismatch, or even a gasket allowed to protrude into the passage channels can cause a break in the clean air flow stream and be very, very counter productive. Next comes the carb that you are going to use, and here, you need to match the carb size with what the engine will require in CFM flow. To small of a carb, and although it may meter fuel very well at low RPM, come high RPM and the engine is going to starve for fuel. To large of a carb, and although the engine will have plenty of full/air at high rpms, the metering of fuel to air on at low rpms is going to be a mess. Trustfully, when push comes to shove, Carbs are a pain in the ass to get dialed in just right, no matter what manifold they rest on. If the engine does not have fuel injection, going to such out the gate will be the best bang for the buck (closed end system). If the engine does have fuel injection, then depending on the Edelbrock manifold design, may find that it will increase the motor power for the given range that you are doing most of your driving. So to answer your question, if you are just going to swap manifolds alone (use the stock carb), then you will need to make sure that everything is lining up with lips between the two, and the carb is re-tuned for the new manifold. |

I appreciate it. I presently have a fuel injection rig and honestly I can't work on much of it. I can do routine maintenance but I like having a carb, when both are equally set correctly. I will go ahead and look at this and see whats the deal. |

I guess I will go ahead and see but from what I could see visibly on the manifold it was clean without gasket or any marks from being attached to the engine. |
| engines are a bunch of pieces put together that are designed to compliment each other and perform for a long time. just bolting on an intake manifold may work, if it's the right manifold designed to work with the other pieces in the rpm range you are wanting your improvement in. if you think that makes it sound like a long shot.........you could be right. |
