1940 CHEVY CHASSIS BUILDERS GUIDE
First and most significantly, plan your Project
1940 Chevy Coupe Build
Know the way you wish to have it to look when it’s finished.
This shall be repeated routinely on the grounds that it cant be mentioned adequately. Do you intend for it to be hi-tech or ancient kind? Billet Wheels or Painted Steelies? Pr-street? Pro-traveling? Is floor scrapping low?
Will, It’ll be a low mileage exhibit car or a limited-access highway flyer for pass nation cruisin? Set up parameters based on truth and not just wishful pondering.
Blown colossal Block Motors hardly ever make just right long-distance cruisers. Tremendous inch wheels look incredible on some cars however tradeoff trip remedy for appears through requiring quick sidewalls that do not soak up street shock. Don’t forget there’s a tradeoff to the whole thing so save your self-time, money and aggravation with the aid of planning your venture for your new Chevy Chassis.
Secondly, preserve in mind that you’re building a car. You’ll be utilizing old steel body, however manufacturing process 60+ years in the past were not very precise and there are minor versions in all these ancient cars and minor changes are seemingly on every step of the vehicle, so plan for that and scan match everything earlier than you paint or powder coat something.
We picked Fatman Fabrication frames our 40 chevy
They are constructed of two” x 4″ x .188″ mandrel-bent rectangle tubing with 1″ x 2″ x.A hundred and twenty” mandrel-bent x-member. They’re made to follow the usual form and form and to suit with usual body mounts, include radiator mount holes, bumper mount holes, the topside physique mount holes, and strolling board mounts.
Let’s go over each and every aspect of the 40 Chevy Chassis:
Font Suspension, Brakes, master Cylinder & power Brake options, Rear Suspension, Sway Bars, Rearends, Engine/Transmissions & body conclude
Fatman frames or Chevy Chassis come ordinary with Stage II suspension, which makes use of coil springs and stock MII shocks. The experience top is approximately 4″ scale back than inventory peak and monitors width comes stock (56 half”) width. Tire to fender clearance is sufficient on these cars, however, awareness must be paid to your wheel and tire spacing. 7″ or smaller wheels match the first-class.
Stage III coilovers are our most widespread choice for the entrance end Chevy Chassis seeing that mild height adjustment, first-class shock, and just right looks that match the polish stainless tubular manage arms that is normal on all frames.
Air Ride experience is available in either “cool” journey (Stage IV) or Shockwave (Stage V). “Cool” ride has the air spring in a position of the coil spring and the shock established at the back of the manage arms. Shockwaves are just like how a coilover looks and mounts with the shock inside the air spring. A compressor process is needed with both options.
One more consideration with Air experience is the Brakes. On the grounds that the air springs are better in diameter a caliper with the banjo bolt on the backside as a substitute for the aspect is required. The Wilwood caliper choices a Wilwood or endure complete process is recommended.
Manual Rack & Pinion steering normally on any of our “roller frames” and our Chevy Chassis, but power steering is on hand as an alternative and is most likely advocated. Shocks are as a rule the most important element in experience remedy and handling of an auto. Shocks are the “brains” of the front suspension considering that it controls the speed of the suspension itself. NASCAR teams take dozens of shocks to the monitor, however handiest a pair pair of springs. Monroe fuel charged shocks are typical and do an excellent job, however, Carerra and QA1 have adjustable shocks that we will provide that enable you to fine-tune your ride alleviation and dealing with your automobile.
something to maintain in intellect as we talk about brakes in your Chevy Chassis is that some men and women use larger brakes to “fill” their new colossal billet wheels or as a “gown up”, without even given that the safeguard part. 1937-40 Chevys in most cases weigh about the equal as an inventory Mustang II automobile, however, don’t forget greater brakes are higher brakes. You have got never heard of anyone say “if I had much fewer brakes I would have particularly nails that vehicle”.
Fatman Fabrication frames and Chevy Chassis come normal with ECI or similar kits that use early GM “big” piston calipers and provide 65% extra braking potential than the inventory Mustang II. These 11″ disc brakes use OEM constituents which are effortlessly serviceable units making use of elements that are available at your local auto materials retailer, will have to you ever have got to make an emergency restore. 5 lug 4 half of” (Ford pattern) is usual. 5 lug four 3/4″ (Chevy sample w/12mm x 1.5mm metric studs) it is also available however use the above stated small piston GM calipers.
We’ve a number of choices for your Chevy Chassis from Wilwood, ECI, or Baer Brakes.
Wilwood has an aluminum GM giant piston substitute caliper with the banjo bolt int he proper location ad it nonetheless uses the OEM brake pads. Entire Wilwood huge brake kits are available that uses aluminum hubs, 4 piston aluminum black clipers with eleven”, 12″ or 13″ rotors. Drilled rotors and polished calipers are also choices on these kits.
No matter which Brake option you opt for, be certain you may have security on your mind

master Cylinder & power Brake options:
We use common automobile steel brake traces for brake plumbing. These D.O.T. Authorized, show fine-looking, and will final a lifetime. Whilst you see the bent traces you’ll be able to swear a computer did it. We also use braided stainless flex hoses from the frame to the calipers. Metering valves are used with disc/drum applications, 2psi residual strain valves are used between the master cylinder and discs and 10psi residual pressure valves are used with drums.
We use Chassis Engineering leaf springs on the rear. They are able to be set up to accommodate either the ordinary or extremely-low journey trip heights. They furnish first-class trip fine and adjust for changes in load (humans, gas, and luggage) very good. They are nice for inventory width frame but don’t work well with frame rails which were narrowed to accommodate higher tires. Four links rear suspension (both parallel or tri-link) is used with coilovers or Air experience. We, in general, suggest the air Rid on the rear because of the flexibility afforded with the variable strain. Coilover don’t accommodate changes in load good as they have given spring cost that may be relaxed in an empty auto, now not heavy adequate in auto loaded with additional stuff. The Air Rid can also be set for a cozy experience and appropriate trip top at the push of a button regardless of the load. Bear in mind a compressor fill package is required with an Air Rid suspension so there may be an extra price and there is less exhaust routing field. The floor will ought to be modified within the trunk subject when utilizing coilovers or Air experience.

Rear sway bars come commonplace on all automobile frames to support control body lean. We seldom use a front sway bar on account that of the practically 50/50 weight distribution and excellent roll middle on Mustang II based suspensions. If making use of a giant block motor then one is recommended. Additionally, if you want a “G” computer that has quality cornering qualities, then select this alternative. Plus, if the “mid existence obstacle” guy with the new Corvette thinks that your “ancient” auto is no suit for his, you’re going to have something for him. Pay attention; some journey excellent suffers to make it control higher. Again, this all goes again to what form of car you are building too.
If utilizing rear disc brakes with coilovers or Air Rid suspension with both disc or drum a prostreet kind rear sway bar is required.

Fatman Fabrications regular “curler” frames and Chevy Chassis incorporate an eight” Ford rearend. These are used rearends from Ford Granada passenger automobiles which were sandblasted and primered. If you are going to take the time to rebuild the brakes, substitute the axle bearings and seals you will have a good serviceable rearend with a collection of “highway” gears with a view to final for many concerns free miles at a very minimal fee. We can rebuild brakes and replace bearings and seals should you want.
9″ rearend are to be had and are custom made to the proper width. You could get brand new apparatus sets in Trac-loc or open configuration. New drum brakes are also on hand for the 9″ rearend.
For the People looking to build a show automobile, an elegant aluminum 9″ or rapid change rearend must be considered.
700R4 and 4L60 overdrive transmission are general as a result of the stoplight friendly first apparatus and the overdrive for the freeway. Be conscious although, overdrive transmissions will, on the whole, require a rear equipment change or a new gearset that we will supply for you. With the 700R4 we do have to be aware of if its casemount or tailshaft mount. We also will want the measurement from the Transmission to the Transmission Mount on the Chevy 4L60E as they are able to vary. With handbook shift transmissions we will be able to need the dimension from the Bellhousing to the Transmission Mount, the width at the widest point and if you’re going to use Hydraulic or Mechanical take hold of Linkages. The option cost on grasp pedal setups do differ in keeping with what setup you utilize, any frame rework and if you wish to have us to mount a snatch master Cylinder
All frames and Chevy Chassis come entirely assembled (except Air experience compressor methods and fuel tanks) and sprayed with grey or black lacquer primer. As a choice Reflections Paint and body saves, Inc. (placed in the identical elaborate) has a body priming carrier that entails the following steps:
Phosphoric acid wash
Epoxy primer is packaged in a style of different colors. The black epoxy is probably the most general of the entire colors and does now not require a topcoat when accurately applied. When catalyzed and sprayed, the black epoxy offers the same “satin” look as any new sheet metal elements proper out of the manufacturing facility.
This primer will also be scuff sanded and topcoat painted if favored, but now not essential. This painting method is advocated by means of the paint brand and is the excellent undercoat process available in the marketplace today.
