My roadster build
Finally figured out how to get a pic on here. This is the '27 roadster I worked on for several years. Started with the glass body, which I split down the middle and widened 8". You can see the added width in the firewall and on the rear apron. Frame rails were 2' x 6" mild steel. Made saw cuts through 3 sides to bend them, then welded up the saw cuts. Rear diff, rear suspension (Satchell link 4-bar), wheels and brakes from a Continental Mark V. The 2.80 gear was retained because I was building this car as more of a cruiser. I had a 4.30 pig under the bench, but decided it would be too much. 429 and C6 from a '68 Ford. '29 A radiator shell surrounding a 4-core Walker copper/brass radiator. Self-designed and built IFS made from 1 1/8" chromoly tubing, using Chevy pickup control arm bushings and Aldan Eagle coilovers. Mustang II power rack and pinion. Built the car on a 117" wheelbase so I would have plenty of room for the 18", 7-blade OEM steel fan, viscous drive and shroud. You may be able to see that all the added length is between the front of the motor and the radiator. I had a 2 1/2-gal Moon tank that was scheduled to go in between the frame rails at the front.
Measured with a dial indicator, zero bump steer through 9" of travel (4 1/2" in bump, 4 1/2" in droop) in the front suspension. As viewed from the front, the inner tie rod pivot point lined up with the lower control arm mount at the frame and the outer tie rod pivot point lined up with the centerline of the lower ball joint. Everything swung through the same arc, so it was all happy with each other. 3 1/2 degrees of camber gain at full bump. Steering arms were fabricated from mild steel and heli-arced to the Lincoln spindles with additional gusseting.
The 1 1/2" square tubing you see at the bottom is the floor of the car. I built it to accomodate a 6'-6" driver with plenty of elbow room afforded by the 8" width addition. A Jerry Kugel 90 degree brake pedal assembly was mounted under the dash, using a 'Vette master cylinder and Midland-Ross booster. I had seats from a VW GTI and windshield from an MG that weren't mounted yet when this pic was taken.
New spring cups were fabricated and welded in at the rear to accomodate Speedway 5" diameter coil springs so that the car could be dialed in. Their springs are available in rates from 125 to 600 lbs/in.
The 429 looks lost in there doesn't it. I'll try to post some detail shots of construction if I can find the pics.
