Melling camshaft

dodge freak said

I would look for a cam with 112-114 lobe centers. It won't make the most peek power but give a strong idle and a wider power band.

Those melling cams are lower lift, should last 100,000 miles on the street if they are made well.

Even the stock 340 cam with 114 lobe centers might be what you are looking for. Give it some compression.

Indeed. This was the advice I gave shortly afrer joining here. A wide lobe separation is much better on the street. But I got buried in arguement, so I gave up. While the narrow lobe center will provide ultimate peak power, the power is exactly that. Peaky. Using the wide lobe centers makes the torque curve much flatter, picks the low end torque up a LOT, makes the torque curve longer and aids in creating a strong vacuum signal at idle resulting in a smoother idling engine, all while giving up a very small amout of total power.
