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.

A 1973 cast iron intake (1st year EGR) - 47 lbs. A 1972 HO Intake without the crossover - 14 lbs.
|
Weighed a 70s cast iron intake once, 42 pounds, aluminum Edelbrock Torker, 17 pounds.

Well, I'll never know now since its on the car.

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. |
Bare Tomahawk - 11lbs
69 4bbl - 38lbs 71 4bbl - 40lbs 76 4bbl - 43lbs just for the heck of it, fully dressed 65 tri-power with carbs and lids, waterneck, thermostat, etc -59lbs All weights done repeatedly on a bathroom scale, not sure of accuracy |
I had to lift my 73 intake off the engine once in an awkward position. My god my back hurt after that.
|
1968 4 bbl, 40 lbs. (bathroom scale)
|
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:) |

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

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
