For a daily driver and highway cruiser, I wouldn't bolt the 350 to the stock 4-speed. It can handle the torque but it's so noisy you cant hear the radio. I've rebuilt it several times with the same result. Remember to use header wraps or a sock to save your plug wires. Also I went with 3 core radiators to cool the V8. Just about as good at the 4 core but cheaper.
