1972 MG B GT with LS1 power

Started on May 23 by Keith Tanner

When your wife says "you know, I'd really like an MGB GT with that V8 rumble", you don't ask questions.
So here it is. It's a rust-free California blue plate special, just waiting for me to upset the purists.

The plan was to get the car sorted out (more or less), then heave a Ford 302 into the engine bay. "I'm not chasing massive horsepower and all the expense and trouble that goes with it, just giving the car a character change." At least, that's what I originally said. Then things took a bit of a turn, and now it's a fully re-engineered car with about 6 lbs/hp and fairly shocking performance from the LS1 engine. Yee, hah.

Out of the paint booth!

After months of sporadic bodywork, I finally managed to shoot some paint. It's amazing how the car is transformed - the flares are smoothly integrated now and the crusty old black has been replaced with a deep shine. Along with ...

Start of the bodywork

With the car up and running and on the road on a regular basis, it's time to cover up those exposed wheels. The track's been widened by 4", so the fenders have to flare to match. An original Rabbit donated ...

First drive with the V8

It's alive and mobile! The car left the garage for the first time in a couple of years. No high-speed test, this was a "let's make sure nothing seems too wrong" drive. But still - IT MOVES! Before long, the ...

The suspension is done, so the car can now sit on its own wheels. This is a fairly major step, given than the entire front end was basically lopped off and a new frame created. The rear has a custom ...

It's in!

Okay, it's just a test fitting. But the complete engine with accessories and the transmission are all in the car and within an inch of their final resting places. That's Janel helping to muscle the big engine into her little ...

The Camaro is dead.

Step 1: dig the car out of a snowbank. Step 2: find a good battery. Step 3: Disassemble! The engine, transmission and front subframe all came out from underneath the car. It was a long day with a number of ...

Camaro, be frightened.

I'm pretty much done with the suspension work on the car, so the donor Camaro will be coming apart soon to provide an engine and all the other greasy bits that will make this car truly exciting. Slow Car Fast.com/MG ...

Blow the dust off!

I've been busy working on another project, and the MG has been neglected. No longer! I've started working on the poor little car again - which, by the way, has been named Nigel Brimstone by my wife. It's her car, ...

302 = not enough.

Plans have changed. The 302 has turned into an LS1. We started putting LS engines in Miatas at Flyin' Miata and I kinda turned into a fan of the engine. So instead of using an old Mustang for a donor, ...

So what's the rumble going to be? Small block Chevy? Windsor Ford? Nailhead Buick? AMC 401? LS1?

This is an almost perfect V8 candidate. The world's not losing a concours early 70s BGT, it's gaining a Badass GT.
