Driving My tunnel Ram 69 GTO
Lets take my 1969 GTO for a ride.... It will never be "finished" but it's a blast to drive. It has a Tunnel Ram with two Predator carbs on. Just an awesome combo to run on the street. It Idles great and makes more top end HP than the Edlebrock dual plane and 850 Holley ever did. It has a richmond 5spd, Moser 12 bolt, 33 spline axles.. I've had this car for 25 years...
A few things I have not had out or off the car: The rear quater windows, the steering column and the A- arms (though they will be getting replaced with tubular at some point. Did 90 - 95% of the work myself... NO it wont please everyone... but it doesn't have to... I'm smiling!
