1977 MG MGB

1977 MGB V8 Roadster

I bought this British racing green roadster in 2011, proceeded to remove the heavy, weak 1.8 liter 4 banger and 4 speed transmission and then engage in a year long assembly process to install a lightweight all-aluminum Buick 215 ci (3.5 liter) V8 and 5 speed Camaro box.

The performance transformation with this engine and drivetrain is truly exhilarating . It now accelerates with the speed of a modern high speed sports car and can cruise comfortably on a highway at very low RPM's. I have gotten 29 MPG on long highway trips.

Unfortunately, I just turned 75 and cannot get my 6 foot plus frame in and out of the car the way I used to. so it's time to give the car a new home.

The MGB however is in great shape. All the conversion bugs have been sorted out and its really a pleasure to drive.

The car was painted by the previous owner just prior to my purchase. The usually objectionable black bumpers were painted the same color as the car and I get a lot of conplements on this feature.

The external changes I've made to the car are as follows: 2 rows of tasteful louvers in the hood. A V8 insignia on the rear deck (the same badge design used in the factory V8). A dual exhaust system which required centering the gas tank.

Everything on this car works! The lights, signals, accessories, heater, blowers, horn, handbrake, wipers, everything!

I went way overboard on the money I spent on this project with over $25K invested.

Here's a list of the performance modifications I added to the B:
