Thread: Stock intake vs. alum. intake

Tweet

Someone once told me that the stock intakes for the 429's were almost as good as aftermarket alum. intakes. Is this true? The weight of the motor is a slight factor in this project. I'm putting a 429 in a 1970 mustang. How much weight would I be saving with an alum. intake? Also, what would the tourqe specs be? Thanks a bunch.

It depends on what aluminum intake you use as to the performance gain. Which intake you use depends a lot on what else is done to the motor. What do you have for a cam, ignition, heads, etc.??? When you buy an intake follow the manufacturers recomendation on torquing it. Weight savings of cast iron to aluminum on a 429 I would guess to be 12 to 15 pounds.

you can get much better aluminum intakes on a 429 than the stockers.... i know that ford even made an aluminum intake for the police interceptor 429s... the weight of the stock manifold was 75lbs and the weight of the aluminum was 50lbs... get a set of aluminum heads too and you've reduced motor weight by 100lbs

go for aluminium,edelbrock rpm gives good results,but check hood clearence!
