Is there any interest in a 455 2 barrel carb and intake?

ggoudas

What i mean is should I post it in Parts or is it not worth it?
Thanks

I would be surprised if anybody wants it. Somebody might want the carb.

I would say yes it is worth asking. The SX came with a 455 two barrel. Might be plenty of others also that would want it. Post a picture with any numbers etc on it. Someone here will tell you exactly what it is.

Maybe I am way off but I think someone would want it. Sounds like you are a cool dude that isn't looking for crazy money.

Jesse Gave me one years ago and I have yet to use it. I'm don't believe it really helps gas milage

You won't sell it if you don't offer it for sale!

List it here and anywhere else you might think of, like FB marketplace if you use it. Worst case is nobody's interested, then you can drop it at the junkyard and not have to wonder whether it was actually scrap!

no1oldsfan

Post pictures.

It came out of a 68 or 9 definitely a Delta 88 and I saved the Posi Pumpkin, I thought it would fit my cutlass but Monza said not going to fit. Interesting car had buckets and a center console. I took the engine and the rest was a big mistake.
Thanks I will pull it out of the scrap truck run and get some pics of numbers. Should I continue to post it here or choose another place?
Sorry I just noticed other replies while I was typing.
Thanks

I think it is neat, cuz it's the way they used to do things... big ole 455 torque monster with a simple 2 bbl carb. Now a days it's little bitty 2.7 V6's with turbos in a big F150 etc. But is it worth anything? Prolly not, except to the guy who has one already and wants a spare.

redoldsman

It would cost a small fortune to ship that thing across the street. I would advertise the carb but scrap the manifold. But then that is just me.

RetroRanger

I had the same for sale for a while. Eventually i gave away the carb and junked the manifold. Still if i had another i would offer it up.

no1oldsfan

I guess I am out of the loop. Apparently I saw value in it. Sounds like I was wrong.

I would possibly be interested in the carb if I could see pictures. There are some that I can use and some not.

Thanks

If you post the manifold on a boat forum it may sell to someone needing a very heavy anchor.

The 2 V carbs were 650 cfm same as small Holley 4v

Hey ggoudas, do you know what rear end the posi pumpkin came out of?
I know someone looking, depends on what it came from.

Not even close. The large bore 2GC used on the BBO was rated at 500 CFM, but there's a huge asterisk on that. 4BBL carbs are rated at a pressure drop of 1.5" Hg. 2BBL carbs are rated at a pressure drop of 3" Hg. You can't directly compare the two, but you can be 110% sure that the 2BBL is more restrictive.

66-3X2 442

Curt Anderson figured the math on the large base 2GC and it was around 350 CFM give or take. If they were 500 CFM,the 66 tricarb would be 1500 CFM,no way that's correct.

joe_padavano

The tri-carb doesn't use the large bore BBO 2GC. The small bore 2GC is a lot closer to that 350CFM number. Even then, the issue is the pressure drop used for testing. Higher pressure drop causes a higher flow measurement. The reason for using the higher pressure drop when testing the 2BBL is because it is more restrictive than a 4BBL at W.O.T., so there is more of a pressure drop. I've seen some data that claims that these 500 CFM large bore 2GCs flow about 390 CFM at a 1.5" Hg pressure drop. When you have multiple 2BBLs, the pressure drop is less because there's more venturi area, so the 1.5" Hg differential would be more appropriate. Test three large bore or even small bore 2GCs at 1.5" Hg simultaneously and you'll get a LOT less than 1500 CFM. You'll probably get a lot less than 1050 CFM for that matter.

66-3X2 442

I said the large base 2GC carbs and the center tri carb is a large base unit. The bore is 1 1/4 on the center carb and 1 5/16 on the ends units.

joe_padavano

You are correct about the center carb, my mistake. The fact remains that the large bore 2GC is rated at about 500 CFM when tested at 3" Hg and has been shown to flow about 390 CFM when tested at 1.5" Hg. I think we're in violent agreement. In any case, the claim of flowing the same as a 650 Holley 4BBL made above is pure fantasy, which was my whole point.

66-3X2 442

I haven't seen all of the 2GC examples out there but the end tri carbs @ 1 5/16 is the largest. Yes I agree the claim of flowing the same as the Holley is fantasy.

I can possibly use it depending on price and if the choke pull off bracket is held on with 2 screws. It's hard to tell with the rods in the way. Let me know. Thanks

oldolds88

the biggger 2 bbls are used in some circle track classes. places like jet will buy cores.

ggoudas

I can take a better pick for you. I looked at the black plastic at the base and it looks like 2 that hold it on. I am not sure on price because of shipping. What is it worth to you?

66-3X2 442

I can use it for $50 shipped. You can ship it via USPS Priority Mail medium flat rate box for about $15. That will be about $35 for the carb but that's about all I can pay because I'm just using it for parts.Just let me know and I'll get you paid. Thanks,Mike

ggoudas

Let me know if the pics show the 2 screws correctly for you.
FYI This carb came out of a 69 Delta88 with 455 and a Posi rear, car had 68K on it

66-3X2 442

No,in the third picture the black rubber diaphragm is in a bracket that should be screwed to the air horn with two screws. I think it is,so I hope you saw my offer,let me know. Thanks

oldcutlass

If you want to sell it, put it in the classifieds with an asking price.

ggoudas

Got it there are 2 and I


will check shipping $ soon and get back to you.

Lesson Learned post in line more with what i want to accomplish.
Post 1 ---- Is there any interest in a 455 2 barrel carb and intake?
Post 2 ---- What I mean is should I post it in Parts or is it not worth it?
It took on a life of its own but I believe I have it sold soon. I feel better about not junking it and as for the money will I think $50 shipped is fair.
I just need to make sure I can ship for about $15
thanks

ggoudas

Posi Came out of a 1969 delta 88
What I found out
16B41 GM LC 267 is stamped on the ring gear teeth
16 and 41 see it with the B in between.
That is your gear ratio 2.56 41 divided by 16 = 2.56 ratio
Sorry, I thought I replied to this but if I didn't I am now
