Air Cleaner Stove Pipe / Heat Riser question

[Steve @ BROTHERS]

Our '70 4x4 was very original when we got it. One owner and only 55,000 miles, but it did have headers. Now we're putting it back together with manifolds and trying to determine if it was supposed to have a "Stove Pipe"? From the looks of the air cleaner, it DID have one from the factory. The air cleaner has the large open fitting on the bottom of the snorkle for a pipe. Does anyone have pictures of the small block stove pipe setup? Does anyone have a stove pipe setup for sale? Could use any help I can get with this one too. Current pics of the truck are below:

Is that the bad boy that the center link I got you is for?!? Man 'o' man that truck is gonna be sharp!!

[Steve @ BROTHERS]

Indeed it is !!!

Hey, Thanks again for going out of your way to get me that centerlink. It's at the powder coater now, hopefully it won't get lost like the last one.

Here is my stovepipe setup, sorry! its not for sale. You will need the pipe and 2 piece (I think) collector that fits around the exhaust manifold. I might be looking for a new collector myself as mine is beginning to crumble. But they sure do work on those cold mornings!

I'm just glad it was the one you needed!

Steve, awesome truck.
What is the best technical source for the correct procedure on restoration of these trucks?
I would like to know the step by step. Also how did you prep and finish your axles?

nu2-72,

The factory shop manual and assembly manual are real good resources when you're doing a restoration on your truck. This board is an awesome resource too. I wish there was a real good book written specifically for trucks with info on details like proper colors for components etc, but there's not. There are great books for Camaro, Chevelle, Corvette and such that are good on detail stuff, and most of the info correlates with trucks too. I've used them plenty of times to figure something out. One thing I do is take pictures and notes during disassembly so that I can use them to put things back the way they were when it comes time to reassemble. Take good pics of little things like clip colors & locations, hard lines & hose routing, wire routing and what types of fasteners are used. Any of the details you think will be important when you put it back together. I always try to determine the original color of components too. Make notes so you can put them back the way they're meant to be.

That's some of what I do. I'm sure there's plenty of ideas floating around this board also. Like I said, this is an awesome resource right here.

Here's a link to one on ebay that Gee Emm posted.
Has a little more than you are looking for, but does not have the piece that fits around the exhaust manifold.

The 'base' plate mounts between the engine and ramhorn. The outer part that surrounds the ramhorn is mounted to the base plate with small screws. The lower end of the hot air pipe is attached to the top hole of the outer surround part with 2 screws. The top end of the hot air pipe goes into the snorkle.

Two things:
I have my engine out and just detailed the pieces you want to see. The outside piece I painted with Eastwoods factory gray exhaust paint. The inside piece appears to be aluminum so I left it alone. I'll snap some shots tonight.

The other thing I'd like to point out is that you have a rams horn style exhaust manifold on the LHS of the engine with the angle back dump. I'm pretty sure that all 4x4s had the rams horn style manifold that dumps straight down the middle. BOTH the manifolds I took off my working engine when I pulled it had a part number and "RH" in the casting. I'll take shots of them too for you.

Man having those pictures of everyones Stove Pipes is really helpfull, thanks, keep 'em coming. As far as the angled dump on my LH manifold.... I had a straight dump on there first but took it off because it was way to tight against the enginge mount. After asking around a bit, it seemed nobody has a real clear answer on whether or not a 4x4 should have a straight or angled manifold, so I opted for the one that gave me some clearance. Since we're trying to do a spot on resto on this truck, I'm willing to change it if somebody can provide a reasonable amount of proof that it's supposed to be one-way-or-the-other.

Steve, as far as I can tell, I have nothing in writing, just experience. All 4wd's were striaght down dump on both sides. I have parted many and had alot of 4wds. Also if you go back to the straight down, the stove is a little different on the bottom on the straight dumps. I don't believe I have any right now I will double check. I may have the pipe.

Experience works for me Let me or JC know if you have anything

[sactoC10]

Steve,

I have a pipe, but not the stove part that surrounds the manifold. I am sure that you probably already have the air cleaner assembly... so I am not sure if what I have would be worth your time.

I was not going to sell it, but maybe we could work out some sort of trade if you've not found anything yet? Let me know, I always need something! I'd rather swap for a part anyway!

I'll check my stash of parts to see if maybe I have the stove assembly.

[pickupman]

Steve, I will check when I get home tonight or in the morning, and give you a call tomorrow. I have been thinking and I may have it all if it is still there.
Bill

[Steve @ BROTHERS]

Bill,

I'll keep my fingers crossed that you have an entire setup. Just let me or JC know. From the sounds of it, I'm gonna need a LHS exhaust manifold too. Can't use the one I have here because it has an alternator bracket cast into it.

I'll wait to hear back from you, Thanks.

[mrein3]

Here are the pictures of the stove pipe I promised. Since my engine guy is a month late I have had lots of time to paint things.

[mrein3]

OK. I'll try it again...

[mrein3]

Here are my exhaust manifolds. This truck was NOT stock when I got it. However one of the parts house catalogs I looked at indicated the LH and RH manifolds are the same. Mine appear to be the same but one has a "61" and one has a "62" in the casting. The part numbers and the "RH" cast in appear to be the same.

Another data point. I ordered the LMC dual exhaust kit a couple of years ago. It bolted up to my "stock" manifolds with NO monkey business.

[skokie]

Ok I am gonna ask the dumb question here. What is a heat riser/ stove pipe used for?
Thanks

[Southpa]

Its for those cold starts in the morning. Heat from the exhaust manifold is collected, rises up the stovepipe, goes into the air cleaner and is then sucked right into the carb. When I first bought my truck it had one of those K&N racing air filters installed. First cold winter morning the truck took a ridiculous amount of time to warm up properly. I traded the K&N for the traditional air cleaner w/ heat riser etc. and once installed I could basically just start up and drive after only a few minutes.

[nu2-72]

I have also been looking for a heat stove and shield. Anyone have a decent set left?
PM me with price and condition. Thanks.

Steve, if you go with the Vette manifolds, you will have to cut off the generator mounts. Also, one of the Vette manifolds comes with a hollow stainless tube that goes right through it (the right hand side I believe). Some guys use two left hand side ones because they fit either side.

I cut my gen. mounts with a hacksaw and then used a die grinder to make it look stock I followed up by sand blasting and painting and you can't tell they are not stock. I also port matched using a fel-pro 1404 exhaust gasket to help them flow better as per Brzizinsky racing www.castheads.com Check their 2 into 1 exhaust with mandrel bends that makes more hp than duals. I installed that on my Blazer and noticed a significant difference. I also used their gasketless manifold-exhaust interface piece thingy....hasn't leaked yet!
