Who makes a dual carb intake for a GMC 228?
If the 4 barrel makes me look silly, I would go with the dually
Infact I would prefer it. The dual carbs just looks tough.
Everybody has intakes for the chevy.
Where can I get a dual for the GMC 228?

If anyone has one I'd think it would be Dave Aos of Cedar Hill, Texas 972-291-4391. He brings a FRACTION of the ones he has to the Decatur, Texas swap meet each year (Feb. 24-27 2012).

Bad Hot Rodding

They also make you look ignorant because the L6's long intake runners cannot possibly deliver fuel equally from a large , centrally mounted 4BBL carby ~ if you want to go fast , use multiple carbys , one for each intake port (3) is the best but for ease of installation and tuning most go with two carbys.....

' you canna change the laws of Physics Jim ! ' .
 
Thanks for the input guys
Guy out in Arizona sells the 5 carb Howard, were you can run 2-3 or 5 carbs.
How cool is that?
Anything would be a huge improvement from what she was

Remember :

More than one carby per intake port is time , $ & effort wasted .
 
I would have to agree Nate.

Thanks for the input

The exception to this is the Chrysler slant 6. It was offered with a Hyper Pack which used a Carter AFB 4bbl for carburetion and along with other factory goodies ran like a scalded dog. The intake manifold was what Chevy and Ford inliners could only dream about.
 
Bypass Oil Filter brand/type ?

Hey there

I became cureous when i saw your engine picture and have a minor question . What is the brand and model bypass oilfilter you have hoocked up here ? Did you had to make any adjustments to make it work ?

Apriciate Martinius.

Hi ctzr1,

if you find a good place, for your intake needs, could you please let us know, where to go and get one?

As my intake is pretty rough, i might as well go for the dual carby option, instead off finding a used one. I fixed it with cold metal for now, but i don´t like
this kind of repair.:(

TIA

I sent you a PM blue flame with the link.
But for everybody else I got the idea from inliners.org in the tech section under full flow oil filter. Its there for GMC and Chevy.cause as you know they are different.
although these engines lasted a good long time with a bypass filter system of filtering what, 20% of the oil. I thought how long would it last on a full flow.
Then you can buy a bypass filter head and a fram filter.
I just have to mount mine yet.
I was probably going to weld a bracket to my Alternator bracket when I get it and mount it there.

When I find one I'll let you know.
But what I am finding out is that if you go with the Fenton Exhaust Headers you'll need to go with a Fenton Intake because the flange thickness is different from say the Offenhauser.
I am sure you could probably rig and grind to make em match up but I did not want to have to do that. Fenton makes a 4 barrel intake why don't they make a duce or a tri?
 
As a fellow 228er, I'm loving what I'm seeing!

I, too, have drooled over the idea of dual carbs on my 228. I asked a fellow who sells stuff on this site about intakes, but never got boo back, so...
I would imagine that Patrick's has what it takes since he rebuilds these. Good luck!
 
Hey Charles, is that for a 228? You can find stuff for Chevy engines all day long, but GMC stuff, not so much...

Great picture, though!
 
Looking for the items needed for these motors is good because we get to see other sites that have Thinks that may or could be modified for work. Just look at Big Tims manifold on his truck.
Check out this site and look at some of the adapter plate goodies further into the site. http://www.vintagespeed.com/

Thanks ccharr
I have been drooling over vintagespeed web site.
I would love to bolt down a couple /few stromberg 9super7's to my GMC if I could find the manifold.
Chevys... up the ying yang but nothing for that looooong motor.
Hopefully with the attention this thread is getting somebody is gonna come thru.
I will probably call Patrick's tomorrow to get his input.thanks
 
Paul,

Not sure just went to a site that use to have them listed but it now states they no longer carry them.

Best get in touch with the Guy Evan talked about there in Texas for the manifolds.

I will call him too. This site is invaluable for information but nothing can beat ..picking up the phone
Thanks ccharr
 
4 barrel on a GMC 228

I down loaded this picture a couple of years ago off the net of a 4 barrel on a GMC 228.
I always thought it looked cool.
If its your truck.. Thanks for the photo, It looks awsome
I hope the performance is just as cool.
