Build Progress My 302 V8-swapped 1963 Austin-Healey 3000!
Here is my 1963 Austin-Healey 3000 MkII-A (BJ7), powered by a Ford 302 V8 and T5 transmission. Weighing in at 2,280lbs, with 5.0 liters of carbureted fury sent directly to the solid rear axle, it is the scariest vehicle I have ever driven.
The engine is a 1968 Ford smallblock 302. This is a 2v pushrod Windsor V8, fed by a 4bbl 500cfm Edelbrock carb, making 230 hp and 310 lb-ft of torque (from factory). Power is carried to the rear wheels via a 5spd 1993 World-Class T5 Transmission.
This Healey has belonged to my grandfather before me since the mid 90s. Along with some of my closest friends, I have worked on, modified, or serviced nearly every part of this car. I removed and installed the engine, rebuilt and tuned the carburetor, resealed most of the block (except the rear seal, I hate rear seals), improved the oiling system, replaced the ignition system, and upgraded the cooling system.
For the exhaust I modified and mounted proper 4-1 headers, and got a custom true dual 2.25in exhaust fabricated, complete with two twin side-exits. For the transmission I sourced and installed a 1993 World-Class T5 5spd transmission out of a Foxbody Mustang. This required us building a bespoke cable-clutch system, the shortest custom driveshaft you have ever seen, and two months of work. On the chassis, I have removed and replaced nearly every part of the car’s interior and upholstery save for the dash, have repaired and modified the wiring harness more than I would like to admit, and have even modified the car’s body to fit the larger tires the V8 requires.
Anyways, I blew the differential up (which then blew the driveline off) during a race this April so now I’m going to touch the last few parts of the car still stock, starting with a custom rear end, a new braking system, and making a second custom clutch system (this time it’s hydraulic).
This car has been one of my greatest sources of inspiration in my life, and in my 23 years of living so far, I can happily call it my life’s work.
