A 347 does not have the torque curve of a diesel truck.

My guess is the smoothing that is turned on has all but removed any curve shape.

Even the 482 inch big blocks that I build for towing applications do not have that flat of a curve.

You would have had a better chance of a flat torque curve if the engine had not been high strung. The trend that we see is that when hp peaks are at higher rpms and hp reads higher than torque, the torque peak is high as well and the curve is peakier as well.

By your graph, it reads that at any rpm, your torque is essentially 340 lbft. It just doesn’t happen like that. It’s also not logical that your hp peak was at around 6200 and your torque peak was at 3000.
