Guy Dirkin's - Byers SR100

 

Background to Guy Dirkin’s Byers SR-100

I acquired the car a few years ago.  The car was built by two enthusiasts in the mid 1950’s in the Madison ,Wisconsin area.  The builders of the car followed the brief instructions provided by Jim Byers in his literature very closely as evidenced by the parts used.  In the late 1950’s the car was acquired by a person in Kenosha, Wisconsin.  He finished the car, painting it metallic maroon with gold fogging. He owned the car for over forty years but during those four decades referred to the car as a Devin-Cobra special. He never new it was Byers.

The body was mounted on a 1949 Ford sedan chassis.  The 1949 Ford was the first year Ford offered independent front suspension. The front and rear suspension was 1949 Ford with drum brakes all round.  The 1949 Ford chassis was cut in the center and shortened to fit a 100 inch wheel base.  The rear suspension was also 1949 Ford with stock 4:11 gears.  The car had leaf springs.  The floor of the car was plywood. 

The engine is a 1956 small block Chevrolet, located in a front mid engine position:  You can stand between the front suspension and the front of the engine in the engine bay when the body is in place!  The 1956 Chevrolet V8 was the first small block Chevrolet with an oil filter.  The displacement is 265 cu. in.  The 1956 SBC has no castings for engine mounts on the side of the block, consequently the engine is mounted from the front of the block. For Chevy trivia buffs, 1956 engines were painted red, not orange.

When I purchased the car the body and paint were in excellent condition.  I rebuilt the front suspension and improved the rear springs.  I intended to use the car as a fun summer car.  The car handled quite well, except that the leaf springs would move sideways and caused rear steering.

A couple of years ago the car was scratched by vandals.  I was unable to repair the paint.  At this point I planned to both restore the car and ready the car for vintage racing and track days.  The car will be ready for next spring.  Below is a summary of the project.

Ø      The 1949 front suspension was retained

Ø      The front suspension has modified front uprights which lower the car 2.5 inches.  These should be acceptable to pre-1957 Vintage organizations as they were hand made and could have been made in the 1950’s.

Ø      The car can use both drum brakes and disc brakes on the same stub axle.

Ø      From about 18 inches behind the front suspension, the chassis is new. 

o        The chassis allows for a longer foot box

o        The chassis has a wider seating area.

o        The chassis is very much safer and more rigid

o        The chassis has side impact protection

o        The chassis now has a four link rear suspension with a panhard bar and coil over shock absorbers

o        The tubing of the chassis will be covered with sheet aluminum

o        The side impact tubes will not be visible

o        I retained the original 1949 Ford axle, but also have a 1973 For 8 inch rear axle with a 3.25 ring and pinion as you cannot get gears sets for the 1949 Ford.

o        The Chassis has a fuel cell with rear impact protection

o        The Chassis will has a roll bar with a front bracing tube

Ø      The transmission is a Muncie M22 close ratio, similar to a mid 1950’s Corvette

Ø      The engine, at the moment, is still the 265 V8.  It is probably 220 hp and 270 ft lbs. torque, which is close to stock.  The plan is to retain the 265 cu.in block and build a ¾ race motor.

Ø      The clutch and flywheel are street specifications.

Ø      The exhaust is two side exhausts with 3 inch pipes, with 24 inches of spiral baffles.

Stayed tuned for further updates!
