    Engine Fuel pickup problems

    Car died on me while driving. I could hear my pump starving for fuel (Gauge read 1/4 tank). Had a buddy bring me some gas, car fired right up. I went to fill up and after 9.6 gallons the tank was full (including what I put in on the side of the road). This means my tank should've had around 6...

    Resolved 2004 Mach 1 WOT fuel/spark issue?

    Hello all, I am in the process of recording datalogs for my tuner to get my Mach 1 dialed in. The base tune is dialed in according to my tuner, so he requested some 3rd gear 2,000 to 5,000 rpm pulls. On the first pull at WOT it felt like I hit the rev limiter at ~5,000 rpm. I am not sure if it...

    Engine Dreaded exhaust/ fuel smell inside car

    I know this is one of the more common issues with these cars, but it’s driving me absolutely crazy lately. I rebuilt my 302 about 5 years ago, using the gt40p setup. The car runs flawless when I do drive it, which is maybe once a month. Within the last 6 months though there is a noticeable...
