Intake Manifolds - How Much Do They Weigh?
How much do the various factory and aftermarket intakes weigh?
A lot of us want to replace our heavy factory iron intakes with much lighter aftermarket aluminum intakes. Others have modified their factory iron intakes to remove unnecessary weight, often removing the iron front water crossover and substituting an aftermarket aluminum crossover. So for the sake of comparison it would be good to be able to know how much weight can be saved either by changing intakes or modifying them. Weigh your intake on an accurate scale and post the weight here. Include a picture if you can. After we start to compile a fairly complete list of all the most popular factory and aftermarket intakes I'll edit this post and make up a list for easy future reference.

1972 cast iron intake -- I was surprised it weighed just 31 lbs. . . not like the "battleships" from the Buicks and Olds motors from that era.

I've shipped a number of '67 -'72 iron Pontiac Q-jet intakes and most of them weighed right at 43 pounds packed up in the box, using a minimum-weight packing material (mostly styrofoam) that surely weighed less than 5 pounds. I would say those intakes weighed at the very least 38 pounds and likely a tad more, perhaps you could recheck the weight because 31 pounds doesn't seem right.

A 1973 cast iron intake (1st year EGR) - 47 lbs. A 1972 HO Intake without the crossover - 14 lbs.

I've often thought about ways to cut some weight from my 70 GTO. I like that I've kept it amazingly stock looking, although not numbers matching.
The A/C compressor, Intake, Spare Tire, Cast iron exhaust manifolds, And believe it or not, the combination of the Delco AM FM stereo & console mounted 8 Track combined with all the above are akin to having a passenger in the car at all times. In reality, probably the spare tire & jack are the only things I would remove. Stock is stock, it's the per pound price I pay. |

I had to lift my 73 intake off the engine once in an awkward position. My god my back hurt after that.

I want to think my 73 SD intake weighed 47 or so. They had a much bigger EGR bosses on the bottom than the later 70 EGR intakes did.
Yea the Tomahawks are probably the lightest. I'll weigh my M/T cross ram today for the survey

A digital bathroom scale should be pretty good as long as you're standing on the scale first holding the intake and after that getting on the scale alone and subtracting your body weight.

I was only able to remove 12 lbs by removing the exhaust and coolant crossover, and the unused bolt bosses.

Next time you have it off see if you can get it on the scale.

That intake looks very familiar. Probably all of the extra weight comes from that "cross-over tube", Skip JK (;>) Its "brother" is sitting on the shelf.
It weighs 24 pounds with the same cross ram linkage and 50 pounds with 2 Holley 735 CFM dual quad carbs. Tom V.

For an aluminum intake the Victor feel pretty heavy, alot of metal in it.

Just put a Victor on my car the other day. Didn't think to weigh it first though. It felt quite a bit heavier than the Tomahawk that it replaced
