What 440 intake?

I have the stock 440 in my 78 d300 and I do use it to tow. Bone stock it was very very slow would gtec. In the low 18s installed the eddy performer intake, a set of hedmen headers recurvered the distributor. And msd ignition. And yes the ac is still all there and works great. Truck now runs very high 15s. And she pulls like a beast. Very fun to tow with. I would suggest the performer intake
