367 vs 410 Engines Masters

I am going to speculate that the 410 is faster on the drag strip even if the 367 is geared differently. I say speculate because all I have is a half ***'ed attempt at the curves and an old copy of Drag2000 to plug them into.

Here is the 367 power curve I entered:



And here is the 410 power curve:



My results using a '72 Duster and running iterations for stall, launch, shift and rear gear are as follows:

367 - 11.106@118.0
410 - 11.042@118.5

Not much faster, but still faster.

Here are the results for the 367:



And the results for the 410:



And the settings for the iterations:



It's far from conclusive, but more stall, higher shift points and more rear gear still weren't quite enough to catch up with the bigger motor.

Doesn't mean the premise isn't valid, but I would say for this theoretical discussion, the 410 is the faster motor. In my opinion.

Oh, and I went back and plugged in actual rear axle ratios rather than the speculative ones:

367/4.11 -> 11.106@118.0
410/3.71 -> 11.043@118.6

So the "odd" ratios didn't throw it off.
