After our 1969 Pontiac Firebird was painted, we made the jump to Electronic Fuel Injection using the Holley Avenger EFI system . We were impressed with the completeness of the kit, that it came with not only the ECM, throttle body, and hand-held controller, but also the complete fuel system down to the hose clamps. We used an MSD Pro-Billet distributor for the ignition duties. After a couple hiccups along the way... mostly ground related, our Pontiac 400 came to life and the system worked perfectly. It's easy to set up, tunes itself in learning mod, offers datalogging, expandability, and more. The drivability is sweet, the power is instant, and the car exhibits refined manners. The Avenger EFI system lived up to Holley's claims and then some.

Today we thought we'd let you hear the 490 in the '68 Camaro for a bit, and it sounds killer. It's a stroked 454 with an Eagle crank and rods, JE pistons, Holley oval port heads, a Weiand Stealth intake manifold, FAST EZ-EFI fuel injection, MSD Digital E-Curve distributor and MSD wires, Moroso fabricated valve covers, Hooker headers, and a Vintage Air Frontrunner serpentine system. But the real star is the Comp Thumpr hydraulic roller camshaft kit... (PN COMP K01-600-8). This thing sounds like a top fuel car! More on this engine in an upcoming video, but here's a taste. We love the super-fast throttle response of the EZ-EFI and this Comp Thumpr. Cool.

FAST Electronics recently announced an upgrade to their race-proved XFI Fuel Injection system which adds new functionality to the popular system. Perhaps the most significant advance in the FAST XFI 2.0 system is the addition of self-tuning capabilities. What's even better is that you can send in your existing FAST XFI 1.0 box and have it upgraded to 2.0 at a surprisingly low cost. We spoke with FAST at the International Motorsports Industry Show to learn more.

Many classic and muscle cars were built in an era when automakers used open vents to allow air into fuel tanks. These vents were often hidden over the fuel tank, or up along the fuel filler neck. Back in the day, this was perfectly acceptable, but today, we're much more environmentally conscious. When you convert an old car to electronic fuel injection, like we did on our 1955 Thunderbird, that open fuel vent becomes a source of increased fuel smell as well. High-pressure recirculating fuel systems warm the fuel, returning it to the tank with even more vapor, compounding the problem. In addition, the original vents often do not provide enough air supply for the tank as the fuel level drains. The crew at II Much Fabrication have come up with an innovative solution with their billet Fuel and Differential Vent which allows for sufficient fresh air into the tank, and also incorporates a separator to allow the fuel vapor to return to liquid and drain back into the tank.
