Hi, need some help. I am progressing to the point where I will be firing up my flathead for the first time soon. I have a dual carb intake and am trying to decide whick carbs to use. I have a real nice matched set of Shromberg 97's and various Holley 94's. Now I know that the 97's don't have any provision for vacuum advance and at this point I plan on using a modified Chysler distributor and electronic ignition with a vacuum advance so i guess the Holleys are the way to go. What is the opinion out there Shromberg of Holley.

Thanks

 

cts1954, for all its worth, i use a single holley on new rebuilt 59ab with very good results. have a couple rebuild kits for 94 if needed. don't have lots of experience with dual carbs but wonder if you couldn't tap vacuum off base plate below carb if possible? pete

 

Thanks, I am leaning toward the Holleys but as I have such a nice set of Shrombergs it would be a shame not to use them. The vacuum for the advance has to come from above the throttle plate I believe, someone correct me here if I am wrong so there has to be a fitting. Holley have it Shrombergs don't.


I guess i would not have any trouble selling the 97's but its nice to have the option.

Regards

 

You may also want to consider our custom curved Flathead DUI Distributor. The mechanical and vacuum advance are calibrated for your engine combination.

Dual Weber Carbs or dual Rochester Carbs. I like the look of the Weber carb setup. You can see a picture in LMC s catalogue. You would need the addaptors for the 3 into 4 bolt base.

 

Strombergs are "traditional" but more expensive than Holleys. If your 94's are in good shape (don't leak at the power valve, accel pumps work, shafts tight, passages clean and jetted right), they're OK. IMO, no one except Weber makes high quality 2-bbl carbs that provide clean fuel mix across the whole range , but they are $$$.

Merten, what body parts did you give for those Webers???!!

 

I have to use the Holley or the Strombergs, it's not in the budget, I have to use what I have on hand. Also would be nice to spend $400 on a distributor but I am going to make my own electronic ignition out of the Chrysler unit and I will need the vacuum advance. So I guess I will have a pair of Strombergs for sale.

 

A lot of the guys on the Hotrodders, and the MSN Flathead Forum like the Mopar Dist conversion. Seems pretty easy to adapt, looks more traditional and the price is right. I priced one out at Schucks for $45.00 awhile back.

 

So what do you get for your $45 bucks, we don't have Schucks here but I have plans to make a distributor out of a 70's Mopar distributor, machine the housing so it fits the flathead cover and the shaft is cut and welded to accept the old flathead shaft. Along with the wiring and module you have an electronic ignition that looks alot the original.

 

Ross,
Those Webers are not mine, I just like them. I had a Weber conversion setup on an old Volvo 144 and really like the product.
cts 1954 Those Strombergs should bring a pretty good price. a lot of people prefer them over the Holleys.

 

Keep in mind that you may have to mod the vacuum ports on the Holleys, too. They are drilled for the LoadAMatic Ford distributor, which uses both venturi vacuum and a port just above the throttle blade. I'm using a single Holley 94 as-is with a MSD distributor with adjustable vacuum advance can, and it seems to work OK, but with two carbs it may not.

I also was going to make the MoPar into a flatty distributor. The GM distributors are a lot easier to do, and much easier to work on. (I just always liked the MoPar design, and found a good used dizzy for $10). Changing the springs on the MoPar is a major deal, on the GM it's a 10-second job. The GM also has a longer body that can be easily turned down to fit in the flatty tube. What MSD does is take the GM points-style body (not the huge HEI one) and put the electronics inside it).

I'll just chime in from a Darkside perspective. Don't give me no grief, it's just some real-life experience. In addition to my muscle-car years, I also drag-raced VWs. (11:80s) Don't tell anyone..... I'm a Truck guy today....

Weber Carbs are top drawer in workmanship if you're willing to work with them. Like any Carb they need tuning but they are like watches mechancially...... Excellent craftsmanship.

 

Yea they were the top dogs down at Glamis also. They always seemed to do real well in the sand dunes on the VW Sandrails.

 

Unless the Strombergs have been very well taken care of over the years they are going to leak. Some find that part of their appeal, these same people like to smoke while pumping gas.

The 2x2 Weber setup is $1400 thru LMC and their 3x2 Weber is $1700. I saw a Rebuilt Olds J2 going for compatable.

The Webers have almost infinet tuning when you use their replaceable throats.
I would love to have a pair of the DCOE Side Drafts mounted on a 4Bbl manifold for the Flatmotor.
