Guys, I would appreciate if anyone could help me. I bought a '73 Nova in MINT condition. It has a built 350 with clay smith cams, hedman headers, 4 barrel Holley carb, (unknown aftermarket) heads, flowmaster exhaust, line locks, variable height shocks for burnout or traction. 4 speed auto, unknown gearing. This car came from Florida and was set up for drag racing...! It is literally slower than sh!t, what the hell could be the problem????
