Need advice on a 4-barrel carb
Have an offy 4-barrel intake for a 8ba flathead. What carb should I buy? A Holly 390, Autolite 2100 or what else?

Re: Need advice on a 4-barrel carb
I have used the 390 Holly and it done very well for me, I am building a wcfb,a rochester 4 jet, and thinking about experimenting with the 41oo 1.12 from a big block and installing it on a blown flathead, a 4 barrel is in my opinion the most trouble free and the performance has always been decent.I have used the 1953 version of the 452 Edelbrock and the Offenhauser 4 barrels both have done good.
good luck! Fordestes |

Holley 390 has worked well for me.

The WCFB is the way to go. Small, looks correct, flows at 380CFM. Basic pic

Re: Need advice on a 4-barrel carb
Bill,
I'm running a '52 Olds Rochester 4 brl on an ancient Fenton intake. The Roch is a simpler carb than the Carter but has the same vintage look. No doubt the Carter is probably a more efficient carb. I'm a throw back guy.....everyone else in my crowd is using the Holley 390 out of the box. Charlie ny |

Re: Need advice on a 4-barrel carb
Here is a manual for the Carter WCFB if you want to rebuild it.

Re: Need advice on a 4-barrel carb
Another excellent vintage carb that's harder to find is the Stromberg Aeroquad - only used for a few years on Buicks (I think). I don't know flow, but it's comparable to the Carter.
If you can, get the WCFB for a smaller engine like a 265/283 Chevy - it will be better jetted and sized (the main body is slightly different from model to model) for a flathead than a big Buick or Cadillac.

Re: Need advice on a 4-barrel carb
Back in the early 50's a friend had a 40 Merc coupe with a 276 and a used an early Buick Stromberg 4bbl carb. It had Zeffrer gears in trans and 3:54 rear. You could drive for weeks in 2nd gear. I remember driving it in 2nd. on a long streach of road, kept pushing the gas peddle down slowly and suddenly the the 4bbl opened and it felt like the front end lifted right up. It also had a chopped top with about a 6in. windsheild. What a fun car to drive. Walt

Re: Need advice on a 4-barrel carb
I am using WCFB's on two engines. They are off 54 Buicks. I have one on a 241 Dodge hemi and one on a 276 59A engine. Both give great power,drivability and economy. I have not changed the jetting on either. I did plug some vac. leaks/ports. The carbs are ideal as they are small base and have flow control flappers on the secondaries. No bog. I had a 56 Cad on one before and it was terrible. I was told that this carb was the carb of choice back in the day for flatheads. They sure work for me.

Re: Need advice on a 4-barrel carb
I like the erly Wafb my self, but it's hard to tune, The Edelbrock 500 is my favirite. Don't think much of the 390, run rich. Just mu opinion.

Re: Need advice on a 4-barrel carb
I've been running an Edelbrock 500 on a basically stock 8BA for a couple of years & love it. Set it up using an exhaust gas analyser but basically drive on the primaries so not too thirsty!! Manual choke and instant starting from cold. If I go a week without driving it (rarely happens!) I need to prime the carb as float bowls drain. I'm using an electric fuel pump so not an issue.

Re: Need advice on a 4-barrel carb
I am leaning toward switching my 2 - Edelbrock 94s to a Holley 4 barrel manual choke on my 53 flathead V8. Would you suggest I go to Speedway for the parts?
I plan on driving my 40 as much as I can. Hopefully y The Hooel won't have the gas fumes that the 2 - 94s are leaking. |
