1978 Pontiac Trans Am FAST EZ EFI Fuel Injection Overdrive Engine Upgrades V8TV V8 Speed and Resto

This 1978 Pontiac Trans Am came to the V8 Speed & Resto Shop more like a lame duck than a bird of fire, so our team went to work adding new rear gears, a 2004R overdrive transmission, a roller cam from COMP Cams, and a FAST EZ-2.0 EFI system for better driving manners. The Pontiac 400 engine even received an unexpected refresh along the way. It’s not often to see a Pontiac 400 fuel injected engine, but this car keeps the Poncho power with modern touches.

We sell these parts and can install them on your classic or muscle car, just contact the V8 Speed & Resto Shop to talk to our technicians or to schedule your upgrades, transportation services are available.

Some of the parts used in this upgrade:

F.A.S.T. – EZ EFI 2.0 Fuel Injection System
Royal Purple – Max ATF and Max Tuff Synthetic Assembly Lube
B & M – Converter Lock-up Controller
Tanks Inc – Fuel Tank, HP Fuel Pump and Sending Unit
Shiftworks – Shifter Conversion Kit
COMP Cams – Roller Cam, Roller Lifters, Push Rods and Roller Rockers

Adding some “Bad” to the Bandit!

Calling all Trans Am fans! Buckle up, because V8 Speed and Resto Shop is taking a classic 1977 Firebird and turning it into a pro-touring monster. This isn’t your average T-Top Trans Am – it’s a non-T-Top model that’s about to receive a complete overhaul.

530 Horsepower Heart Transplant

The centerpiece of this transformation is a brand new LS3 V8 engine. This beast pumps out a whopping 530 horsepower, a far cry from the original engine’s output. To handle all that extra power, the shop is also installing a 4L70E overdrive transmission.

Straightening The Curves

But it’s not just about straight-line speed. V8 Speed and Resto knows that a pro-touring car needs to handle corners like a dream. That’s why they’re outfitting this Trans Am with a Global West suspension system. This upgrade will ensure precise handling and confidence-inspiring grip. YearOne 17″ wheels complete the look for any Trans Am!

Comfort is also important, even for a car built for performance. The shop isn’t forgetting about everyday usability. They’re installing a Vintage Air A/C system to keep things cool on those hot summer days.

To keep the driver informed, the classic instrument cluster is being replaced with a modern Dakota Digital gauge setup. This will provide all the essential information in a clear and stylish way.

Follow Along as we complete the transformation of this Trans Am and set it free on the open road!

1979 Pontiac Trans Am LS3 Swap and Suspension Upgrades at V8 Speed and Resto Shop

Posted on by V8 Staff

This 1979 Pontiac Trans Am was originally equipped with a 403 cubic inch Oldsmobile V8, and although it was pretty hot for the time, it just isn’t enough for the owner today. The car came to the V8 Speed & Resto Shop for some high-performace upgrades including a GM LS3 485 HP V8 engine fed by a Holley EFI system, and it will handle better thanks to a Ridetech Street Grip suspension system with YearOne wheels. Wilwood brakes will haul it down in short order. Before all the fun, we had to fix some rusty floors, which was a good time to fabricate a custom firewall for the car as well. Follow along with all the progress here!
