  • HRM article from the 60's on hopping up Ford's inline 6

    Back in the 60's my feeble mind seems to recall that HRM hopped up a small Ford 6, the one with the integral intake manifold cast with the head. In that article I seem to remember that one of the later more radical modifications involved adapting Tillotsen side draft carburetors to the head.

    So the questions are: 1-does anyone have that issue/article, and could you scan it and post it? There may be an inline 6 in my future and I like doing oddball stuff.

    Thanks

    There was also a drag car - Preparation H that used a Clifford intake with 4 barrel that supposedly ran quite well.

      I remember reading the article about the 3 one barrels, but can't find it now. Early 60s as I recall.

      The side draft carbs....I don't remember that. It probably could work about the same way, drill a hole, make an adapter to clamp on with a U bolt, etc. But since you can't use the original center location, perhaps find two or four carbs to fit along the intake passage?

        I'm actually thinking about a different engine with a separate bolt on intake that has separate ports. AMC/Jeep 6. I may get one for free. So my interest was in the side draft carburetors. I know just use Webers. I have one for a BMC A-series engine and 20 years ago when I bought it the cost was close to $500 by the time I got the whole setup. I can only imagine how expensive 3 would cost today.

        I wonder what other side draft carburetors could be had for small $$$. And I don't like SUs. Too strange, so many metering rods and slide springs to get one set up correctly, let alone 3 or more. Of course one good thing if each cylinder ends up with its own carburetor is tuning becomes just like a single cylinder engine. Read the plugs, make changes to the each cylinder carburetor.

        I know cheap usually costs more. But that's the challenge

          It's getting harder and harder to find carbs period, much less sidedraft ones. The exception is motorcycle carbs, since the third world still uses motorcycles and similar engines for the masses it's easy to got to amazon or alibaba or such and find a plethora of side drafty motorcycley goodness.

            This has been some good reading.
            I did know the 240 and 300 cranks are inter changeable, but it was interesting to see using the 240's rods, and custom pistons on a 300 crank.
            And now, that they mentioned the inline six vibrations, I have that in the Indy Racer, and I thought it was a drive shaft angle problem I would have to think of addressing.
            Thanks Dave for posting the original topic up.

              This thread is about the small ford engines, the 144-170-200-250, not the big ones.

              Straight 6 engines are naturally balanced, as long as the crank is balanced to itself, and the pistons and rods all match each other, you don't have to worry about the crank being matched to the piston/rod weight, like you would on a V8.

                Well actually I was just trying to get information on alternate cheap side draft carburetors originally, but that nugget is good to know. I should have known the natural balance, but in cough cough years of playing with cars, I've only had 5 experiences with 6 in a row engines. 4 street vehicles, all daily drivers, all just appliances, and an aircraft tug with a Dodge flathead 6 Click image for larger version

ID:	1302276 That's me about 55 years ago when we just got it running. Man that thing was a BEAST! Go into the woods and just knock trees over. My older brother (4 years) had his driver's license and our father bought it for us to 1 get it running and 2 to do yard work. He intended to buy gang mowers so we could turn all of the fields into lawn. At that point we had 8 acres. It was his way to make sure we knew the value of work.

                And yes that garage was the nicest one I have ever had to use. 24x60, 4 bays, eventually 100 amp 220 service. It served me well during my dirt racing days.

                    Don't hate me, but the late Jeep derivative, a 4 liter from a Grand Cherokee. BTW in this pc world, can we still use that name, or do we have to call it a Grand native American? Let's get Dan Stokes' take on this as he is a master at turning stuff into pc...

                    Anyway, if I get it, it was taken out of the vehicle because the transmission failed. The replacement tranny came with a much lower mileage engine so the guy just swapped it out completely. He's got a good running vehicle again and needs the engine out of the garage. It's his uncle's repair shop garage where he works.

                      Dave: A (somewhat) local guy had an early '50's Mopar, with the flathead six, it had a twin-carb intake, and was running two carbs, each carb was OE on a Ford Escort EXP. (I believe they were Weber/Holley or Holley/Weber?? )

                      There are a number of six cylinder forums on the interwebs, and there are a ton of threads on I-6 stuff on the H.A.M.B. (Jalopy Journal) as well.

                        New, even a Holley 390 and an Offenhauser manifold are outside my idea of small $$. Individual throttle bodies is almost doable, but I am guessing you want carbs and side drafts for the looks / nostalgia. Finding a points and condenser distributor might be the next hurdle.

                        Spitballing here, but if I were dead set on carbs, maybe Chinese ripoff Harley carbs like an S&S Super E x 3 would be about the right size, 3d print the manifolds. Get really carried away and use scaled up 3d prints for a mold to cast the intakes...

                            Tubing manifold is easy, making a distributor work even if it doesn't have one just takes time. Now you guys have me thinking (not a good thing) I know a guy who used to race 6 bangers. I wonder if he still has any parts, in particular he had a 6 cylinder Vertex mag. That would certainly make ignitio easy. No I won't share his name or geographic location. I want to get there first

                            Never considered aftermarket Harley parts. Well other than the Tillotsen HD carburetors. Thinking outside the box (again not a good thing) I wonder what the largest side draft carburetors on lawn tractor engines are. Adjustable low and main jets... 6 of them. I still have a Unisync from snowmobiling days. Hmmmm...

                            Probably end up with 3 1 barrel down drafts on a log manifold.

                            I still have to get the engine first however...
