Thread: trouble finding intake manifold

Tweet

alright so i finished rebuilding the 351 for my econoline.... and i'm having trouble finding an aftermarket intake manifold that fits it.... all of the ones i've found have 12 bolt holes but my heads and factory 4bbl intake have 16 bolt holes.... anyone else run into this problem? if so any solutions?

use your factory intake, there is not too much of a performance gain of going aftermarket.

Matt's right, a factory 4bbl is better than most aftermarket pieces, bigger ports and better port match. If yours was a 2bbl, though, a factory one might be hard to find. I just leave those two bolts out of each side and they work. On one engine I threaded the holes and put Allen plugs in to make it look better.But you're going the other way, so the holes aren't there in the manifold, no problem.

ok cool..... i didn't bother to lookup any specs on the stock.... i probably should have first...... thanks for the help tho.... this is my first 351 i've done......
