As the editor of Street Rodder Magazine and Content Director In Hot Rod Network, Brian Brennan has seen thousands of street rods.
But seeing is not having, and Brennan had a wish for a modern day high-tech 1929 Model A Roadster. Not one to just think about things, he put his vision into motion.
The foundation is a SO-CAL Speed Shop chassis, a Brookville ’29 roadster body. The original power train for the highboy was a combination of a GM Performance Parts 383 (hi-po) with Demon carburetor, MSD ignition, and Sanderson headers running through Magnaflow exhaust pipes and a stainless muffler.
The transmission is a 4L60E controlled by a TCI Transmission Control Unit, distributor harness adapter, remote throttle position sensor, and a throttle-to-valve body cable bracket. Connecting the two is an Inland Empire Driveline driveshaft.
The trip back to Newport Beach took two full days through 104 degree temperature and elevation changes of over 7,000 feet at Flagstaff, AZ. The trip covered 1,952 miles and Brennan reported a flawless engine performance despite the radical temperature and altitude changes. Not only did the power plant perform perfectly, with the addition of fuel injection, the fuel consumption improved. Before the installation the car was getting was getting 15 to 17 miles per gallon and after the mileage went to 17 to 20 mpg. The car has a SO-CAL Step-Boxed ’32 chassis based on American Stamping rails, 107-inch wheelbase, buggy spring in back, and an angled (7 degrees) front crossmember to which a drilled and dropped aluminum Super Bell axle (and spindles) are outfitted with SO-CAL hairpins, and The Deuce Factory bat wings, perch bolts, shackles, and lower shock mounts. The springs, shackles, shock mounts, and spindles are all fitted with Teflon by Hot Rods by Dean. In back is a Currie 9-inch rear end with Pete & Jake’s Hot Rod Parts ladder-bar setup and buggy spring.
The stock GM 383 power plant has evolved with the addition of the XFI Fuel Injection. There is more to come with the future addition of a COMP XFI Hydraulic Roller Camshaft and kit specifically designed for XFI Fuel Injection Systems. The valve train components are lifters (#875-16), rockers (#1318-16), pushrods (#7608-16), valve springs (#26986-16), retainers (#787-16), locks (#648-16), seals (#503-16) and timing set (#3136). The cam specifications are as follows: Part No: 08-465-8, Duration: 260 IN 270 EX, Lift: .560 IN .555 EX, Lobe Separation: 113-degrees. Well, there you have it, a 1929 Model A highboy on Deuce ‘rails built with today’s rolling body and chassis packages. Pearl of wisdom goes something like this: “Roadsters can never hold everything you want, but they can hold everything you need.”
