6 cylinder offset air cleaner - different? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Luvlegs · 01-08-2008, 03:37 AM

I got this from a 71 blazer(?) - This is the stove and pipe for the offset aircleaner.
I have the first mount on (shiny black piece bolted on) - I tried to show in the pics, the area where I have no clearance to match the housing up with that bracket. The corner to the rear of the engine, against the choke housing area is square and looks like it needs to be angled or rounded to fit. There is also a slot and circle in the stove box that looks like clearance for an auto choke rod that would run between the manifold and the block but my choke is on the manifold.
Is there a chance my intake is NOT a 72??? I know the PO but he made no mention of the engine ever being swapped... that said, the valve cover and block are blue, the intake is orange and of course, no color on the exhaust.
Can anyone tell me what I have? Much appreciated.

Luvlegs, My '71 C10 is all original and here is my setup. Hope this helps.

Luvlegs · 01-08-2008, 12:00 PM

aaaawww geeesch... thanks... can anyone recognize my manifold by the choke assembly on it???

Luvlegs · 01-09-2008, 09:20 AM

Ttt ????

Luvlegs,
Boties pics aren't coming up for me here at work so I may be repeating what he posted.

"There is also a slot and circle in the stove box that looks like clearance for an auto choke rod that would run between the manifold and the block but my choke is on the manifold. "

I have a 71 with the 250 . It has the choke connected to the exhaust man not the intake. It mounts in the indention on your exhaust manifold. It may put it in the right spot for the slot and circle you mentioned above.

Hope this helps

Cyclone44 · 01-09-2008, 02:07 PM

Luvlegs,

I just bought a 72 truck 250 off the parts board and it is all original and the same as yours, and the whole motor is orange, Now my 71 that is all original is like the picture by Botietruck....Hope this helps....George

Luvlegs · 01-10-2008, 08:08 AM

Blue - my heater box does have the slot and circle cut in it - but, even if I did put a choke down on the manifold, there is still the raised part on the manifold that prevents the box from seating down all the way and the linkage would not be lined up with the carb...

Cyclone - does your new 250 have the offset air cleaner? If so, I'd be curious to see a pic of the heat riser (stove) box.

So, there must be a different stove for different years? OR, do I need A) to mount my choke on the manifold AND B) get a different intake manifold???
Still lookin' to see if anyone can shed any light on this. Thanks all.

Mt Man Chad · 01-10-2008, 09:15 AM

Hummm - here's a few parts I have like yours!

Luvlegs · 01-10-2008, 09:29 AM

Mt - got any pics of the intake manifold? That's where I have the issue.

Mt Man Chad · 01-10-2008, 10:06 AM

Here my manifold with out the heat riser on it yet. If you need more let me know.

Luvlegs · 01-10-2008, 12:48 PM

I guess I need to figure out what intake manifold I have - it's very similiar to yours but notice the raised part that the lower part of the choke spring housing is sitting on... it wont let the heater box sit down properly. Anyone have an idea? 73 and up perhaps?

Luvlegs · 01-10-2008, 04:37 PM

Ttt

Botietruck · 01-10-2008, 05:21 PM

Okay, I was curious as to what it would look like, so I set everything in place and here's what mine looks like. I do not have the hole in the stove for the choke rod, but I'll take care of that .
Chad, if you could let me know the diameter of that hole, that would be great.

Luvlegs, Here's an idea...go to NAPA and ask to see the choke spring on, say a 67-68 model truck...or car, and then ask to see the choke for a later model, say, a '73 maybe. That might be the only way to find out what manifold you have. It could be a car manifold. Were they different, I don't know.

Luvlegs · 01-11-2008, 03:14 AM

OK BO! Now we are getting somewhere - so yours has no slot/hole....
The one I have, has the cutout slot w/ the hole at the end - which, it appears I don't need unless I swap out the intake manifold.

What is/was the description of the piece you obtained? any ref. to year? Want to just swap? I know I could just cut the corner off mine but didn't really want to wreck an original part (not sure if it has any value) (it has a small bad spot on it though... hmmmmm maybe just cut it off..... Last question - Bo, is that verticle plate in the pic attached permanently in that position? Again, thanks guys!

**PICKMUP** · 01-11-2008, 09:08 AM

Wow! Look at Bo's goodies on that six: AC, PS, PB/air cleaner. Looks like good reference material.
If I see this right, Bo's is a 70 & earlier with manual carb linkage and Chad's is a 71-2 with cable carb hookup...don't know if it matters much.
Chad's is stick...here's a th350 for more reference.

**PICKMUP** · 01-11-2008, 09:13 AM

...OK, maybe here is a pic of th350 in 71-2...
Hmmmm....you guys sort it out. I am not sure of anything anymore!

Luvlegs · 01-11-2008, 10:07 AM

well, 4 different carbs, 2 or 3 different chokes.... PickMUps intake has the raised square choke base like mine but the base area under the carb is either a plate or a different version of my intake....
I've checked several parts sites so far but cannot find any choke or manifold pictures (that are stock) soooo the ???????s continue.....

Side question: Why would one choke work off the heat from the exhaust manifold but the other, off the intake manifold??? Seems like there'd be a heck of a lot of difference there....

Botietruck · 01-11-2008, 04:45 PM

My throttle linkage does have the cable. I have not installed it yet. The carb & linkage is all original. Now the "goodies" are add ons and the air cleaner is an add on.
Luvlegs, I'm not sure what year my plate, or stove came from. The vertical plate is tack welded to the stove. Can I see a couple of good pics of your part? Not sure I want to swap them, but I would like to see what you have.
Yes, your question makes sense about the choke being on the intake, not sure why they did that.

Luvlegs · 01-11-2008, 06:22 PM

I'll take a couple but it'll be late tomorrow or the next day - it's outside and I'm not

Luvlegs · 01-12-2008, 09:23 AM

Here it is. The bad spot (looking at the picture) is on the right side, at the bottom of the corner that would be near the exhaust manifold, it was rounded off by rust before I got it cleaned up.

Luvlegs · 01-13-2008, 09:49 AM

TTT for one more round....

Botietruck · 01-13-2008, 01:02 PM

Luvlegs, I didn't realize there were so many variations on these trucks. Good luck on getting the correct information on that cylinder head/choke issue. Let us know what you come up with.

retodd7711 · 01-13-2008, 01:43 PM

just to add to the confusion. Here's some spare parts I found laying around.

Luvlegs · 01-14-2008, 03:47 AM

well, Retodd7711 I think your's is the correct one for the stove I have - any idea what it came off of? I'm really suprised there hasn't been any definates yet (we're up to 25 posts now). ReTodd, why don't you throw it in a box and send it to me.... for research... hahahaha I was getting ready to cut mine today so it'll fit but now I'm starting to wonder which ones are "valuable" and which are "parts to use"!
