Manual Mach 1 vs Auto Mach 1
Just a comparison, already know which one is faster, don't care by lengths or whatever...
But, what is the difference? I know the manuals have forged cranks, and their redline is past 6 grand whereas (I've heard) the auto's don't have a forged crank and their redline is before 6 grand...is that true? If not, what rpms do they each make their peak powers? And do they both have the 3.55 rear end gear?

RE: Manual Mach 1 vs Auto Mach 1
Manuals have forged cranks, autos cast. Other than that, they are identical engines (cams, compression, etc.) and have similar powerbands.
The 5 speed has a redline of 6,800 RPMs, the auto 5,800 RPMs.
The reason for the difference in engine redlines is the crank. The reason they have different cranks and therefore redlines is because the auto tranny's guts aren't designed to spin that high and live long, so FoMoCo gave the freer winding 5 speed a forged crank so the engine could wind higher along with the tranny.
There is a difference in weight and parasitic drivetrain loss. The auto is heavier and generally pulls about 18% from the crank. The 3650 is lighter and generally pulls about 15%. Those numbers are subjective and open to interpretation, depending on who you're talking to, but that's not out in left field, either.
They both have 3.55's from the factory.
Does that cover it? Not sure what all you wanted to know, but hope this helps.

RE: Manual Mach 1 vs Auto Mach 1
Cool to know,thanks for the info.

This post pretty much sums it up. If you want to know 1/4 miles differences, I give them to you with equal/great drivers for both cars, the manual can run a 13.1/106 stock and the auto can run a 13.6/102 stock. With avg drivers, manual=13.4-13.7/103-105mph, auto=13.6-13.8/101-102mph...this is all based off of articles, drivers themselves and from my personal experience. The main thing that hurts auto's are the stock converter/shift points/shift rpm's.

Also, thanks radaman for the times on each, I kinda figured the auto's would lag behind by a few tenths, I was just wondering then since the auto's make peak power at a lower rpm, if they would rev quicker than the five speeds, but the gearing for each tranny's gear probably evens that out.

RE: Manual Mach 1 vs Auto Mach 1
The manuals have the advantage in choosing its rpm launch and being able to launch at 5K with sticky tires yields some awesome 60' times. Auto's have a weak 1700 rpm converter, thus hindering its launch severely...Manual's will most likely be faster than auto's in stock situations. Now adays, they have awesome 5,6 and 7 speed autos that will equal/beat their manual counter parts

In drag racing applications, autos never miss a shift. Very consistent and easy to bang gears like a wild man. Just something to remember.
