Stroker specific cams?

So, if I understand you correctly, a wider spread LSA is good for fewer gear. Then how does something like my A518 automatic figure into that with its overdrive?

The fewer gears goes back to needing a wider torque curve, so you don't 'fall off the curve' with gear changes..... and the wider, flatter curve is helped by a wider LSA....ooops, by timing events that result in a wider LSA. Keep up torque at the very low RPM end so you get a lower 'low end' of the RPM range, and thus a larger high-to-low RPM ratio of usable torque. It's not as much of a deal with an auto if you are willing to use a higher stall TC, but it IS a big deal with a manual trans.

(FWIW.... a high stall TC kinda sucks for spirited curvy road driving, as the RPM where the TC 'catches' to give just the right amount of wheel torque at a given moment is less predictable. Some modern trannies like those used in the Challenger have worked around the TC lock-up 'mushiness' by locking the TC (or very close to locking) when you go into manual shift mode, to make the engine much better coupled to the rear wheels all the time.)
