I just bought my first model a project, its a 28/29 sedan, Car is pretty much all stock, Im looking to build a full fender traditional style hot rod, I haven't the slightest clue where to start, Ive built tons of muscles cars, I run a custom upholstery business, Im not a novice to cars, just this particular style of car, The first thing i wanna figure out is what I need to get the car as low as possible without destroying the drivability, Any guidance is truly appreciated
First step(IMO) either box the frame completely or purchase an aftermarket frame. The stock frame(particularly with a v8) is relatively weak and twists easily. An all aluminum engine is easier on a frame than a similar cast iron version with only aluminum intakes. Cast iron exhaust on the engine are quieter and generally seal better over the long haul than headers;however headers generally breathe better(produce more power). Suspension and brakes and steering ease would come next(IMO).Good luck and listen to everyone’s input—-then select the one that meets your expectations and abilities to perform as much as possible with your skills and friends help.
Thanks for the reply, I do plan on boxing the frame, probably run a mild sbc, My biggest things are i want the car as low as possible without stepping the frame so much I lose the back seat, A place for the kids to ride is the reason I went with a sedan, Im a pretty decent fabricator, I just know nothing much at all about straight axles other than I know thats what I want in this car
Use a dropped front axle and a reversed eye front spring, that will allow you to get it about 4 inches lower than stock. You also need to figure out about the brakes, disc, drum, master cylinder, power or manual, etc.
A Model T rear spring will drop the back an inch. Check out some build threads to get ideas about suspension mods. Your local area may have a project car to see. Posting it may help you get a look at one in progress. Good luck stay in touch.
A beam (as in I beam) axle has a little bit of give(or twist if u prefer) whereas a tube(tubular) axle has no twist or give which (IMO) reflects in a harsher or rougher ride. When a cross spring or buggy spring or Henry Ford spring is the right length, the shackles with engine,trans and brakes should be at a 45 degree angle with the weight of the vehicle on the ground.Generally, disc brakes that are power assisted will require a booster(usually firewall mounted and not too eye appealing unless u are able to find a small(in size) booster) whereas drum brake master cylinder can be mounted below the floor for a cleaner firewall look.Try to keep the same bolt pattern of the wheels frt and rear. A model a frame is relatively short so a T or A spring will work or coil overs will work also with a pan hard bar to control side movement.Any year early Ford v8 clutch and brake pedals can be adapted to the A frame with 37-40 probably the easiest to find because master cylinder can mount below the floor.
