headers for 92 rmw 350 tbi

Any have part numbers/brand headers that fit a 92 roadmaster wagon with 350 tbi? thanks

Flowtech Afterburners.

Then any other small block header for F or G or A car... With some minor modification...

I have a TBI 350 upgrade kit. Includes headers, large bore TBI, 9C1 injectors for TBI, LT1 cam, reprogrammed computer, extra manifold, and I can get the exhause pipe flanges for the headers, all for $400 shipped. You will have to modify the crossmember for the dual exhaust (just have a hump welded in). You should also get the heatshields for the tank (if you are going all the way to the rear bumper), and under the driver's side front footwell (if you are using 2 cats).

It's like de ja vu....

Fred,thats an interesting idea for duals on our wagons.Did you make it up yourself?Have you ever
installed this setup before?Dammit Fred you had to go and talk about that kit that I want.
Jim

Bet that kit would raise my 170 horsepower 305 to all of 178 or better but it would sure sound
fast.

You could build a 350, and just slip it in. Then you would have a bit more torque too. You could get a used crossmember from the JY for about $10, and have it modded, so you could just install everything at once. I have a couple of flowmasters too.

I found a AC compressor mount from QWIK that allows me to drop in an LQ9 6 litre without having
to notch the frame so thats my plan.And I will be running a 3" single exhaust and hopefully a
6L60E transmission.It seems like the 6 litre prices are slowly coming down under a grand but I
want an engine with under 100,000 miles.Been talking with the guys at Just Chevy Trucks and
they are toying with some very cheap upgrades that put the 6 litres over 500 ft lbs of torque
at around 3000 rpms.
Jim

Is that a 4L60E? The LQ4 is the same engine as the LQ9 except it has a lower compression ratio allowing it to run on regular gas instead of premium. It costs you about 15 HP. There is a 6.2 liter engine too L92 which makes a couple HP over 400 (55 more than the LQ9), and 415-417 lb.ft. of torque (about 35 more than the LQ9). I assume the same mods would give it a little boost in torque and HP as well.l Externally they look alike.

Flash, I am headed in the same the direction, let me know about the upgrades.

You might be able to find a wrecked truck cheep, and part it out keeping the engine and trans for yourself.

There are a few other differences between the LQ4 and LQ9.

Iron heads for early LQ4s
Different head bolts on early ones as well (not all equal length for LQ4)
Different pistons and rods as well.

The BLOCKS are the same, though.

I have some sort of Hedman headers on my '92 Caprice. I can maybe get under there and see if I can read some part numbers off of them when it's bright outside.

excellent

I can tell you that nothing was cut, and there's still room to work on it with them there.

Spark plug changes are a nightmare though, just a warning. Also, they have no AIR hookup.

Summit also sells cheap shorty headers that will fit. They are not the typical long tube headers.

im actually running the headman headers also , but with my stance they do drag a bit pulling in and out my driveway

Ray ,about that part number on your headers.Have you ever heard of a flashlight?It provides
extra light in confined ares to help you see better!
Jim

Jim, I'm too blind for that.

Which headers are you running on yours?

For the guys running tbi cars was the transmission crossover a direct swap?

I also have Headman headers,for the ShavedWoody not sure of the part #

Hard to believe thats the same set of headers.Sure look great.Can I ask how much the coating cost and did JetHot do it?

I really cant remember between $150 to $225.

The headers are Aluminum Ceramic Coated
provides continuous protection up to 1,375°F (745°C ) and will endure intermittent exposure to 1,500° F (815 °C)

Any pics of the install from underneath? Just curious to hire to ditto around the stock crosmember

Sorry, no picz from underneath

the headers are not mounted yet.

I also have the trans cross member from a 9C1 which is for a dual exhaust setup I have under under the 92 ShavedWoody
not the stock Y pipe setup.

From a 94 up chassis, or another 92?

yes

94 to 96 wagon.

You also need to drill two new holes cant remember which side.

Somebody mentioned something about replacing the tail of the tranny

And which heddman ones are those

long tube ill check and see if i can see part number on mine

just went to look at mine cant actually see the part number cause the angle but im try and take a pic and see if i can see it that way , be later tho , im being lazy , lol

No problem, i'm thinking about how well a single exhaust will work with a set of headers, as long as I keep the pipe size right. Now the 9c1 crossover was different I know, but any body have a definitive description of what difference? I'll probably just have one custom bent, but looking into all options.

Do me a favor Did that crossover come with a separate steel bar to relocate the mounting holes?

I got really stupid over the fall while cleaning the garage and must have thrown the bar out, not realizing what it was from. Beer and beer may have been involved in the memory loss, but oddly I can't remember that either!

I'd like to know the dimensions so I can make up another bar size of the bar and holes spacings would be really helpful. to fabricate anew one.

Thanks, Dave

If you guys ask nicely i,m sure JAYSS has all the answers for this swap, i can't remember if he stillhas one or not,.

Nick

I'll do that.......thx

He "had" a crossmember. and relocation bar.

I seem to recall he sold to a guy who subsequently threw the bar out while cleaning the garage!

Sheep got you drunk again,Dave?
Jim

Noooop, I did that all by myself, without help.

I will have to take some new pix of the setup ,
my cpu needs a new graphic cards.
I try to go under the woody sometime this week.I do remember that I used 1/4 flat stock the width of the tranny mount, length can't remember.

There was an actually steel bar that came with the crossmember.

Has anyone used these? Got a manifod crack on the Occ...

I have a set of headers, 9C1 injectors, tuned ECM, LT1 cam, adjustable fuel pressure regulator, large bore TBI, and an extra manifold. I also have the flanges for the pipes. I do not have a pic of all of the parts. I bought them as a set except for the manifold and flanges. I would like $400 plus shipping for all of it.

Come on Fred,you know used TBI parte are not that exspensive!For that 400 bucks you are
including installation,right?

Yes they are on Shammoo. They fit. Keep in mind it will require a custom exhaust system behind it.
I did get the flange ground flat , due to some gasket issues I was having.

Excellent Yeah, I am planning on all new exhaust too. Also have a LT1 crossmember so will go for duals

Does it have a metal bar for the drivers side to reposition the cross over mounting holes? If so, I need the dimensions of the bar.

The crossmember I have just has 4 nuts welded to the outer edges...no bar. Is there supposed to be a bar in the frame?

*bump*

Getting ready to start piecing together a new exhaust setup, anyone ever use the shorty summit headers above? What should I use for a Y pipe since I don't plan on swapping the cross member? Also, this may be a very stupid question, but do headers kill mpg's? I somehow squeeze decent miles out of the car, would rather not ruin that now that we're pushing $3.50/gal again...

Headers will not noticably change the gas mileage. It will have a slightly different torque curve, and hp curve. The Y pipe is problematic. You can run a pipe under the transmission between bellhousing and the trans pan. You will lose the cat by doing so. I have a set of header pipes "franken duals", and the left pipe runs under the trans, under the bump in the trans crossmember, back under the drive shaft, and over the axle (over the axle part is missing). The setup has a pair of Flowmasters on it. It is for sale. You could run both pipes out in front of the passenger's side wheel.
