Stromberg BIG97 and 97 in Jan 2016 Street Rodder

Stromberg BIG97

BIG97 in Street Rodder

Stromberg 97 carburetors ( regular and BIG97 ) have gained some superb coverage in a major feature in January 2016 Street Rodder. It’s all about flathead Ford intake manifolds. Navarro, Edelbrock, Sharp, Offenhauser and more (all of which can work with the BIG97, of course). Written by Ron Ceridono with help from Kev Elliott and Mike Herman from H&H Flatheads, it’s also available online. You might find the online version a little easier to read. Click here to check it out! Here’s a couple of excerpts:

“Thanks to Mike Herman we were able to gather photos of the most popular intake options H&H currently offers for early (1932 to 1948) and late (1949 to 1953) Flatheads. While the manifolds look similar there are significant differences. The positions of the carburetors on two-two manifolds vary and as a result some require moving the generator, others don’t (manifolds that accommodate the generator are often called regular dual, while those with the carbs further apart are usually referred as super dual). By spreading the carburetors further apart they have a straighter shot into the ports and fuel distribution is improved but relocating the generator requires a head-mounted bracket. Some manifolds are equipped with exhaust heat, others aren’t. In cool locales with today’s fuel exhaust heat can help driveability, in hot climates it’s not normally necessary. All the manifolds shown here accept the stock-style fuel pump stand and the oil filler/road draft tube for 1949 to 1953 applications. Another difference is the number of bolts used to secure the manifold. Due to the shape of the runners, in some cases, the number of bolts has been reduced. On the other hand, in some cases, there are more holes in the manifold in the block, but in either case it’s not a problem.

Although all the manifolds shown are good, some manifolds may perform better than others with a given engine combination. The best bet to resolve that issue is to deal with an expert on the subject like Mike Herman.

Stromberg now offers a larger version of the 97. Completely reworked internally, they flow 250 cfm, compared to the original’s 165 cfm.”

 

5/16in fuel lines for 97s

We recently launched some new fuel fitting parts so you can make 5/16in fuel lines for Stromberg 97s. While the stock early Ford 1/4in OD hard lines are great-looking for a typical flathead motor, many people like the thicker lines for Chevys and other applications. This includes us, of course, as our recently launched 9146-BIG 3-into-1 fuel line uses 5/16in OD stainless hard line. And more than that, all our forthcoming new Stromberg BIG 97s are 5/16in hard line compatible. You can see in these pictures how the BIG S-jet seats the 5/16in line and what happens when you try it in the regular S-jet – it leaves no seat for the ferrule. Click to enlarge.

Today we got a tech enquiry from Shane Dale in Australia that covers this very question, so we thought we’d share it here:

Hello, I have three new 97’s that I purchased in 2011 and am finally getting around to fitting up. I will be bending my own 5/16 OD hard line and was wondering what size fitting will screw into the carb? I purchased three 9180K’s and started hand screwing them but stopped quickly as it went tight.

Hi Shane, A couple of issues here. Firstly, 9180K is our 1/4NPT hard line adapter so the tapered NPT thread won’t fit into the S-jet, which is 1/2in UNF – that’s why it went tight. And as you worked out, regular Stromberg 97 inlet valves (needle & seats) were designed with a 1/4in pocket to take the line and the angled seat is positioned so the brass ferrule can compress properly to seal on the 1/4 pipe. If you put 5/16in line in, it doesn’t sit in the hole properly and covers most of the angled ferrule sealing surface. The good news is, we recently developed a new S-jet inlet valve for our 97s specifically for 5/16th line, and we also just launched a pack of compatible ‘Ford Nut’ style compression fittings for them. You need 3 x 9564K-BIG (the S-jet inlet valve) and just one pack (3 nuts and 3 ferrules in a pack) of 9081K-BIG (the Ford Nut for 5/16th line).

All the best, Stromberg Tech.

 

Price cuts for Stromberg fuel lines

DSC_7871We have cut prices on all our current fuel lines, and introduced new ones too – all at far more attractive prices. As part of our relaunch of the whole Stromberg TwoStep Fuel Line range, we’ve spent a lot of time finding new ways to source the parts and the processes needed to make kits at a more competitive cost. And we’re pleased to say, this is the result.

So how much are they? How does $55.95 (or £29.96) grab you, for complete bolt-on 2×2 Stromberg fuel lines (carbs to fuel pump) for Offenhauser 1090 or 1075 intakes? Our new 2×2 RP lines for remote pump are just $69.95 (or £33.29). And you can get our cool 3×2 sets for Edelbrock 1108 intakes for just $89.95 (or £41.63).

We mentioned new kits. If you’re looking at chrome Stromberg 97s (9510A-CHR), you’ll be pleased to hear that you can now get fully polished lines, with traditional chromed Ford nut compression fittings, starting at $85.95 (or £41.63). Check them out on our website – click here.

All these prices are plus local sales taxes, but they’re all significantly reduced. And it goes without saying that all our new fuel lines come with exactly the same high quality for fit and performance as ever – plus full installation instructions and further help via our website Tech Center.

 

Stromberg Chrome Linkages

Good news for all our chrome Stromberg 97 customers. The full TwoStep linkage range is now available with chromed die-cast levers and polished stainless steel. Designed specifically for use with multiple Stromberg 97 carburetors, the TwoStep range of direct and progressive kits covers all of the commonly available 2×2 and 3×2 intake manifolds – principally for flathead Ford, small block Chevy and Ford, plus various other vintage OHV V8 engines. Chrome linkages for 4×2 and 6×2 applications are also available to order.

The new chrome range perfectly complements our popular chrome Stromberg 97 carburetor (9510A-CHR), and chrome fuel delivery parts. With our show chrome models now accounting for a significant percentage of carburetor sales, customers were naturally asking about matching linkages. So we’re particularly pleased that we can offer real show quality chrome and polished stainless pieces….and at very competitive prices.

Designed and manufactured exclusively by us here at Stromberg Carburetor, the TwoStep linkage range combines clean, traditional looks with maximum leverage and huge versatility. All kits come pre-assembled and install in just two simple steps, without the need for extended throttle shafts. Here are just a few of the features and benefits:

Direct linkages available with swivels or rod ends – opposite threaded for easy adjustment.

Versatile progressive linkages allow you to choose when the secondary carburetors open.

Every kit includes two Stromberg ‘Snapback’TM throttle return springs. Wrapped around the linkage end of the throttle shaft, these chemically blacked, stainless steel torsion springs snap the carburetors shut, yet virtually disappear from view.

Every Stromberg TwoStep linkage kit comes with full instructions, and further help with selection, installation and tuning is available at the Stromberg Tech Center at www.stromberg-97.com.

You’ll find all of our linkages, regular and chrome, on the Stromberg website. Click the link to check them out.

New Stromberg linkages – small block Ford and more!

It must be linkage week here at Stromberg. New 4-banger linkages at the start of the week, and now, more for the V8. If you’ve just stepped up for the long-awaited new Edelbrock 5412 small block Ford 3×2 intake, or you’re lucky enough to have found a cool old intake for three 97s on your vintage overhead valve engine, check these out. Our new 9253PRO is a 3×2 progressive linkage that places the carbs 4 7/8 inches from carb to carb to fit the new Edelbrock 3×2 intake for small block Ford, plus early Weiand 3×2 intakes too. The new 9251PRO works at 4 7/8 inches apart to fit Offenhauser 3×2 intakes for engines like Ford Y-block and 49-61 Cadillac. If you’re looking for direct linkages for these engines, simply choose our 9245S TwoStep kit and trim the linkage rod to suit.

In addition, our new 9249S 2×2 is a simple direct linkage with swivels for a traditional look, sized for a maximum 7 1/2 inches from carb to carb so it fits the cool intake from Edgy Speed Shop for Dodge/Plymouth 201/218 and 230 Flathead 6-cyl engines. We’re reliably informed it will also fit the vintage Edmunds intake for Plymouth 6 engines (with 7 inch carb spacing).

Moving up in size a little we have the new 9250S and 9250P 2×2 direct linkages (S for swivels, P for premium with rod ends). Both set the carburetors a maximum 8 5/16 inches from carb to carb and are designed specifically for the recently announced Offenhauser 1080 2×2 intake for 1949-63 Cadillac motors. Good news is, they also fit the Eddie Meyer 1932-48 ‘low-rise’ intake for Flathead Ford (at 8 1/4in carb spacing).

Prices are US$49.95 (and UK£26.43 + tax) for the 9249S and 9250S, and US$105.95 (UK£54.13 + tax) for the 9250P. Both 9251PRO and 9253PRO kits are US$175.95 (UK£92.46 + tax).

Designed and manufactured exclusively by Stromberg Carburetor, TwoStep linkage kits combine clean, traditional looks with maximum leverage. They come pre-assembled and install in just two simple steps, without the need for extended throttle shafts. Check out the following features:

    • Die-cast zinc SuperLink lever arms. All other parts stainless steel – even the rod ends and lock nuts.
    • Two new Stromberg ‘Snapback’ throttle return springs, which wrap around the end of the throttle shaft. These chemically blacked, stainless steel torsion springs snap the carburetors shut, yet virtually disappear from view.
    • For a smooth, lightweight look, 2×2 kit swivels are positively fixed by a small e-clip, and the small black set-screws have knurled ends for a strong fix on the stainless rod.
    • P kits have special swivels and bolts, developed to clamp the rod ends tight with a small blind hole in the head. Simply insert a small rod eg, a hex key, to stop the swivels turning while you tighten the lock nuts.
    • Progressive kits have opposite threaded rod ends for easy adjustment. Just spin the rod to adjust for the correct lever angles. The primary lever has three mounting points to change when the secondary carburetors open, and you can pull the front carburetor or push the rear one open to suit individual applications. On the top setting (as supplied), the linkage will start to open the secondary (end) carburetors at around 50% primary (center) carburetor throttle rotation. Lower holes will open the secondaries sooner.
