Slant 6 offi 4 barrel intake

-
Offy first offered that manifold back when there were still WCFB four barrels around, and it will take a WCFB four barrel as is. Maybe some early AFB's, too (I remember the hi-po 273's carb base had extra holes so it could mount to the 273's intake). You need the adapter for a modern AFB, Edelbrock or Holley - all of which have a larger base bolt pattern.

Those old WCFB's didn't flow many CFM's and they would actually work pretty well on a slant six if you could find a good one.

I'm pretty sure the throttle bores in the OP's manifold have been opened up. Been a while since I had the carb off mine for a look see.

Correct. It will also take the first generation Rochester four barrel. The "4Jet".

Ya, but where could u even find a fair priced Roch.
But what I really like to get is a 350 or 400 cfm blow thru carb that I use with or without a turbo

There are a lot of decent priced ones on ebay. I'd get a two barrel adapter and run a holley 350 or 500.
 
Great carb, blow through or not
New Carburetor 38*38 2 Barrel For Fiat Renault Ford VW Dodge Toyota Pickup Jeep | eBay
Pretty close to 400cfm(supposedly, 2 bbl rating).

This is the synchronous barrel "DGAS Weber" clone. Night and day improvement vs the progressive DGV, especially under boost

I have one on a blow through 4cyl at the moment. Kick down on a slant might be a challenge
I have a weber on there now

Is that the 32/36? That's a really good carb and easy to work on. I had some issues with the 32/36 under boost but great otherwise
Can I blow thru this carb ?
6 to 8 lbs of boost ?
 
Yes, I've had mine at 8. Supposedly they're good to 15-20. You'll need the nitrophyl floats, which it probably already has. If not I can send you a set
Wow, that is sweet
How do I find out if has the floats ?
I would love to get a set from U . Just in case
 
We had one o them, blasting out a tri-Y set up. Fun car , drove it to bike week, in 90, Late at night, man, we had fun!
We've had nothing but fun with this car so far. I could have left it stock and still be havin fun.
 
What type or size turbo would u recommend ?
My exhaust is already modified for a turbo
I just need to find a simple set up
I've done turbo 4 bangers, no slants, so I'm sure there are others that will chime in. However, for simplicity I'd do a cheap Ebay T3/T4 hybrid with integral wastegate and V band exhaust. The one below is on the small side, but great for a daily driver and is what I have.
Something like:
T04E T3/T4 .63 TURBO TURBOCHARGER COMPRESSOR 300+HP W/ INTERNAL WASTEGATE V-BAND | eBay
 
I can't find any info on this mani I just bought
Looks small for my 225 but was "supposedly" on a 73 Duster
Also not sure on what adapter I will need
Mahalo for any info, C
Wanted to put in my 68 Valiant
Maybe turbo ?

I need one of those, I wanna so bad change my 1 bbl set-up to the 4 bbl, and I'm in possession of a good turbo to top it off.
Anyone hook me up with where I may find an intake for a 4 bbl on the 225??

Why not start a parts wanted thread. That's your best bet.
 
I got a GENUINE WEBER 32/36 DGAV ('Weber' Cast in multiple locations, Made in SPAIN: supposedly better metallurgy for longer throttle shaft service life than clones with stickers) like 63spf's post, will be putting it in the FS section as I can't use it. I needed a DFAV (mirror image) that pulls (strangly) to right. As stated these are great easy maintenance carbs for 2bbl apps. They flow under the 390 CFM 38/38 DGES but are progressive.
