Broad question from a rookie
Here's what gearing does. This is a dyno of a 360 380hp create engine.
Say your gonna floor it at 20 mph.
If you had 3.73 rear gear with a 2.74 1st gear
Vs 4.36 with 2.74 1st gear. At 20 mph the 3.73 will be at 2500 rpm and 4.36 will be at 3000 rpm. If you look at the dyno graph with the 3.73 your acceleration will start with 181 hp and the 4.36 will be pulling from 230 hp.
That a huge 50hp difference.
The 4.36 gears will always be higher up in the hp curve compared to the 3.73 making the 4.36 quicker until you run out of rpm.
Now if you add a 4" stroke to the otherwise same as 380hp combo. It would basically have the same hp curve but 500 rpm lower.
So 230 hp would now be at 2500 rpm.
So a 360 with 4.36 gears at 20 mph and 408 with 3.73 at 20 mph will both now be pulling from 230 hp.
So basically you got to gear it so your into your engines powerband or stroke your engine to lower your powerband to work with less gear.
