Been wanting to change out the stock intake manifold on my 460 for some time now. Finally picked up the Intake i wanted Weiand 8012 Weiand Intake Manifolds
but ive never changed one of these out before. Ive been searching this forum up and down for a detailed set of instructions but havnent found anything close to complete.

Im still green when it comes to really working on my truck and have no one to teach me. So if you all could explain to me how to do this or give me tips on what to do and not to do id really appriciate it.

It's a forum dedicated to the 460.

 

It's been a while since I've done this on a 460, so I'll lay out some generic instructions:

-Unhook your throttle cable from the carb. Unhook the spring from the carb to the intake, unhooke the tranny kickdown. Remove the carb.

-Next you'll want to unhook any vacuum lines you have going to your manifold and any ground wires.

-You may opt to remove the distributor and the waterneck, but I don't think it's necessary.

-I believe there are something like 8 bolts that need to be removed (but really, I can't remember on the 460).

-Next, you'll want to pry the old intake off.

-Now you'll want to tape off/cover the head ports and put a piece of cardboard down in the 'valley'. You do this so when you're scraping all that old gunk and sealer off, it doesn't go somewhere you don't want it to.

-Now you're at the half way point (you'll want to install a valley pan if you need one, can't remember if the 460 does or not though, otherwise, you'll just use gaskets). I prefer to use RTV Black for intakes, so get to sealing and regasketing and start putting back together in the reverse order of how you took it apart.



Really, it's not too hard at all, regardless of how green you are. I was in your shoes about 4 years ago, and was pretty intimidated (but on a 400), but once you really dig in to it, you'll realize there wasn't much of anything to worry about.

 

Wow thats a huge help. Still have a few more questions tho.

So i should just rtv the whole thing instead of a gasket?

I keep reading mixed opinions about whether or not to leave the egr valley pan in. So what should i do?

Im planning on doing the valve covers at the same time and get the impression those are pretty darn simple.

I also dont have a tourqe wrench so how hard should i wrench em down? Something like snug and then a quarter turn?

Thx in advance guys!

 

I use both RTV and gaskets.

As for the valley pan, I use them, but not combined with intake gaskets.

Valve covers are simple, 7 bolts and they're off. Only tricky part is if you have an A/C box, then those bolts are hard to get to, but I just attack them from the bottom, reach my hand up and feel for the bolt and use a 1/4" drive ratchet...maybe a small extension if needed for clearance.

As for torque...without a wrench, I usually go to snug with a 3/8 drive and go 1/4-1/2 turn oast that.

 

Awsome. While im changing the manifold out are there any other things that i could replace to save myself some trouble? Or even just make it look nicer. Things like picking up a chrome thermostat houseing. Or even anything i should make sure to inspect when i get the manifold off.

Your a lifesaver

 

I'd replace vacuum lines, paint the valve covers, paint the tstat housing...things along those lines.

 

IF anything all the vacuum stuff is what im most worried about. I know almost nothing about all the vacuum lines, how they run, where they run to, ect. Wheres the best place to buy vacuum lines? Napa or an auto store?

 

For your gasket I would use Permatex Right Stuff. I used this on my 390 and have never had a leak of any kind. It comes in an aresol can like cheese whiz and is easy to apply. See link below.

I didn't have any luck with my chrome thermo housing. It had an o-ring in it and I had nothing but leaks. Changed back to my factory aluminum one with a gasket and no more leaks. 429CJ in my Torino, but same engine family, also running a Weiand Stealth but for CJ heads, love the intake.

 

I would use the valley pan. but instead of using the rubber ends use a thick bead of Permatex or RTV.

Also being as you are new to all this and wanting to learn I would pick up a Haynes Repair manual. That will give a guide with pictures and specs. Also I would borrow or buy a torque wrench. With aluminum intakes they need to be torqued correctly. I know alot of people don't torque them but I have seen alot of people have problems.

 

What brand was that thermo houseing? I wanted to pick up some chrome valve covers too. any suggestions?

By the way im incredibly jealous of the cj 429. Sounds like one hell of a tourino.

 

I would get alluminum valve covers, the chrome ones seem to rust up pretty quickly.

 

I was wondering about that. The cast aluminum looks damn good too tho. So any idea who makes a good one? IYO

 

Do not use silicone around the intake ports, just some around the water ports and under the ends of the manifold if you don't want to use the factory rubber ones.
