I haven't had 4.10 gears but I really like my 3.73 with my t45. They make a decent balance of acceleration and power. Plenty easy to spin tires. I run out of 1st a little over 35. So that seems about right.

It doesn't rain much here and the roads are terrible when it does. It gets really dicey in the rain. 1st becomes almost useless.

I have almost 100hp more than stock. BigNSlow has more than that. So our opinions are skewed. He's rolling with a lot more torque too.

I would hate have a really short 1st gear though. As it is I can slip it in 2nd and roll slow at about 10mph also.

This isn't necessary on the auto or possible on the manual. In the manual you have no fluid pump to 'force' the lube. The manual relies on the gears themselves to sling the ATF all over the place inside the case. Yes, all of these Tremec trans, the T45 & the TR3650 both run ATF. Just plain off the shelf ATF.

The cheap fluid was one of the selling points for me when swapping to the manual. I wanted a cheap trans with cheap maintenance. $300 for the trans and a $20 fluid change with a longer interval than the auto. I'm sold.

I had 3.27 , 3,73 and 4.10 on manual swapped cars and the 3,73 is the best all around gear with a stock 4.6

Thanks for the info guys. As you can see, I know very little about transmissions but I'm getting there.

I also have plans to put stage 2 cams. I'm planning on staying naturally aspirated, just building the motor a little. Does that change the optimal gear?

cams with manual trans are more forgiving than the automatic trans wich usually need a higher torque converter stall.

If you want a good cam the comp cam 262ah is a good choice.

So I wouldn't regret 3.73?

Would the 262 give me the choppy idle?

That's what I have. MHS stage I heads with stage II cams. I have the slightly different Bullet ground cams. They have Comp grinding their cams to a slightly different recipe now. I've never bothered to learn to speak cam so I don't know the difference.

They are way different than stock cams. The stock cams are really linear, make torque early, and shut down almost altogether around 5400.

The MHS cams that I have seem to have two modes. Super easy cruise mode which is what you get anytime you're under 3k. There's no torque under 3k so you can only cruise in that range. Over 3k switches the engine on almost like old school VTEC. lol All of a sudden it throws you back and it doesn't like to stop pulling. The power doesn't drop out until somewhere north of 7k.

You really shouldn't spin a stock bottom end over 6500. . . . . Two weeks ago I got crazy in 1st gear and it went really high. I don't know how high the tach hit the bottom of the Marauder cluster I have. It doesn't have a peg. It just hit the bottom. lol So 8k? Power fell off that time and it made a crazy noise. Maybe the valves were floating. I've blipped it over 7k a few times and it still wants to pull at that time. I really need to ask Mo to turn the rev limiter on. lol

2nd and 3rd gear pull really nicely. With the 3.73 gears and cruising at 70 you can downshift to 4th for moderate passing. Jam it in third for, listen to the song of my people, serious passing.

With a manual trans you do not need such a high gear due to the first gear ratio. , I always found that 4.10 made the first gear almost useless. 3.73 is a good compromise .

the 262 will give you that lumpy idle due to the lsa but you need better valve springs and should degree the cams (like any cam swaps)

I definitely don't want a useless 1st gear. Plus I'd say about 35% of my weekly driving is highway and a larger percentage is country highways, so I really don't wanna be screaming at 70 mph.

With a manual trans you will be running the same rpm at 60 mph with a 3.73 than a 3.37 with auto trans.

Hey Pier, got a suggestion for future manual pedal builds.

I've been daily driving my box for the past couple of weeks due to my Volvo being out of commission (surprise) and finally got properly acquainted with the 5 speed which brought out a bit of an annoyance.

I've noticed that the brake pedal is positioned further away from the gas pedal than what I am used to with an automatic. I used to be able to go from brake to gas and back without having to lift my heel off the floor. With manual I can't do that. Now I actually lift my foot off the floor to hit the brakes. Seems like I lose a split second braking this way. Once you get used to it it's not so bad but from the beginning it feels a bit awkward.

I'd like to suggest moving the brake pedal maybe an inch or two closer to the steering shaft or perhaps just bending the arm over to the right more. I think clutch pedal can stay where it is. IMO it would make for a better driving experience.

As soon as Volvo is back on the road I'll pull the pedals out and do some testing to see what I can come up with.

The guy I bought my car from altered the pedal placement slightly in this manner, but not nearly as much as is being suggested.

I have fat feet, so I like things spread out a little.

The distance in betewen the clutch and brake pedal is pretty much how the stock mustangs one are. The brake shaft has to remain like that because of the brake booster rod so there is so much I can bend at the bottom to try to bring the brake pedal closer to the gas pedal.

Ford used many different shape of brake pedal shaft on our car over the years . They range from straight to slighly bent like the one pictured from my 2004.

I'm getting stock mustang assemblies any time soo so I will take pictures of the difference.

I was thinking of using a longer brake pedal pivot support pin and just using a spacer to take up the added space.

Something like this perhaps?

Here is a reference pic of what the pedals look like in a Mustang.



The clutch pedal is fine where it is imo. Since left foot only controls the clutch pedal it's not really important where that pedal is in relation to the other 2.

I'd rather bend more the pedal shaft than extending a longer pivot that could brake or twist the pedal shaft during an emergency stop and cause an accident.The tube that align the shaft would need to be modified aswell and I'm not too crazy either.

I would not move the clutch pedal either since it need to be straight to the quadrant shaft .The square hole dosent like too much side play .

Let me get my stuff here and I will come back with something else .

Oh no worries, this was just a suggestion, you do your own thing.
