I'm going to make a Formula Ford racing car. I have a body, an engine, correct wheels and tires, why not! I started with a Roxy toy from Hong Kong... I had to make my own chassis so I did just that in 3 hours... I think next time I'll use a smaller diameter tubing. That's it for now... Patrick

I have a inline-4 Ford engine. I think it's a 2 liter OHC, but I'm modifying it into the FF1600 cc engine. It's orange plastic. Maybe from the AMT McLaren Mustang.

Chassis looks good and the body is surprisingly detailed.

This is going very well. The suspension went together well and I got the ride height good... yup coming along. Patrick

Here is the R & D Unique / Mini Exotics Ford B.D.A nice casting and even better white metal carbs and exhaust... Chris

Very cool Patrick!
Like my '69 Barracuda, it's a phantom race car. That's cool.
I notice you used a Renault gearbox. Virtually EVERY Formula Ford used a Hewland gearbox built in a VW Bug transaxle case. But the Renault would work too. Lotus used that transaxle in the Lotus Europa. Is it from one of the Matra kits? No rule that ever said a Hewland HAD to be used. The engine was spec, the gearbox was not. So use what ya got. Or as racers say it..."Run what ya brung!"
I also note that the head is not the BDA twin cam from Mini Exotics that you show above. The Twin Cam would be great for a Formula B/Formula 2. But As you show that know Patrick, the Formula Ford being a spec class requires the pushrod Ford Kent engine as used in the Cortina and Escort (and a number of other cars) and a single down draft Holley/Weber 2bbl carb. The engine block is correct either way, because BDA and Lotus Twin Cam engines used Kent blocks. So where did you get the parts (head, headers, valve cover, intake manifold, etc.) to convert the twin cam engine to the Kent crossflow Ford?
I give Roxy Toys of Hong Kong credit for doing a decent job of representing the McLaren M7A, at least well enough for you to create this very believable phantom FF out of it. It makes a fairly pretty FF.
What wheels are you going to use? Rules for FF require Ford 4-lug stamped steel stock factory wheels. The later Continental Ford class allowed use of cast wheels with slightly wider rims along with a 2 liter engine instead of the 1.6l. Engine LOOKS the same on the outside. Which do you plan on making this?

Dusty, I figured you might have noticed that this was a Pinto 2 liter block. I screwed up and have the plug wires in the wrong location. The transaxel is sorta made up as I ran outta my Heller Hewlands (I had a Renault trans on my Lotus 18 FC). Where did the parts come from? Well, my spares box. As for the wheels, I'm using the Tamiya Lotus Super 7 wheels that I have been saving for about 7 years just for this project. Thanks all for the kind words. This model represents a '78 FF regional racer.
Patrick
PS- Come to think about it this should depict a FF in 1970 or so. Right Dusty?

Didn't look close enough to notice the 3rd shaft bump on the left front side of the block. But you HAD told us at one point that you were going to use a Ford SOHC engine. I even walked past my 2.3 block (1/1 scale) today. And there are Ford 4 cylinders with the plugs on the right side of the head, just not Kent 1.6l Formula Ford engines. For a Kent they should be between the exhaust ports and the plugs near vertical. But it can fool even a guy who has Tech Inspected a few thousand Formula Fords (or at least a lot fewer cars many times each). So what if it's been a few decades since.
Perfect wheel source. I have a Tamiya Lotus 7 in the inventory, but it's been a while since I dug into it. It seems to me that Lotus 7 kit has a Kent non-crossflow head engine in it. Switching the intake to the right side would fix that and probably be less work than what you did.
Formula Ford is still a popular class. Although Swifts (and all of the copies) have dominated since the early 70s when the 1st prototype was brought out to Willow Springs raceway for testing (then called an "ADF"). Other engines are being played with for Formula Fords now.

I remember when the ADFs ruled FF. A yellow car...Barry Blackmore?

Looks pretty good Patrick! Water line outside of the body to keep from burning the driver on the hot pipe. Factory Ford 4-lug steel wheels with appropriate size tires with tread. (Story related to that below) Sprint car K&N air filter on the 2 bbl Holley-Weber carb. Fuel tank would be under the seat, so it's not visible. That roll bar brace is chrome or other plating (typically nickel) so it's not part of the frame, while the main hoop is gray like the rest of the frame, so the brace is removable, that's normal for Formula cars of the 60s and 70s. Period "Wire Wheel" SCCA sticker on the side under the water pipe. No rear brakes yet and the seat belts should be 6 or 7-point, not 4 point. Both are pretty easy final touches. Then it will pass Tech Inspection! Regardless of that. it's a cool model. Nice job!
