Drivetrain confused...gears

gonna switch to 3.73....what's my tooth size?....all that mumbo jumbo has confused me

General karthief · May 23, 2018

Yea, I got a head ache when I tried to figure that out when I went to 355's, I found a conversion chart that took tire height and gear ratio and trans type and gave me a tooth count for speedometer gear, I ended up with a black gear.
tire rack got me the tire measurement,
This may help http://www.tciauto.com/tc/speedometer-gear-calculator/

oh man, that just confused me even more, but thanks!

General karthief · May 23, 2018

Took me a couple days and a bottle of aspirin

justin82 · May 23, 2018

no kidding....I just need to know if I have 6 tooth or 7 tooth

General karthief · May 23, 2018

I fairly certain you have a 7 tooth drive gear.

justin82 · May 23, 2018

kinda sure, too..but didnt want to get the wrong one

justin82 · May 23, 2018

while, someone is responding back.......if I upgrade the TB to a 65, and the MAF to a 60......do I need to replace the intake manifold as well?

General karthief · May 23, 2018

What's your stuff now, stock?

justin82 · May 23, 2018

yes...stock intake....only upgrade is shorty headers and midpipe

Mustang5L5 · May 23, 2018

No, but don't expect a huge SOTP feel.

As for speedo gear, shine a flashlight up the speedo hole in the trans and look for color

Green = 8 tooth
Yellow = 7 tooth
Black = 6 tooth

justin82 · May 23, 2018

so I can replace the , TB and MAF without doing the intake?.......and where is the hole?...is it in the cabin?....or underneath?....thanks man

General karthief · May 23, 2018

Naw, in reality your intake and heads are limited, that maf upgrade is ok but the tb is going to be restricted by the intake opening, you could waller it out to fit the 65 mm tb but your not going to gain anything, wait and get a explorer intake.
how far are you going to go with this? Have a goal?

General karthief · May 23, 2018

You have to pull your speedometer gear from the trans and peek inside the hole

justin82 · May 23, 2018

I love my car, guys.....thanks is for the help, always!...I just want to get it back to the factory 225hpor maybe 250hp....what are the accepted video extendions....was gonna try and send a video...oh well

General karthief · May 23, 2018

That question is better answered by someone more techie than me.
i still have to pull start my computer like a lawnmower.

justin82 · May 23, 2018

I guess my goal is to just be able to have confidence, if some ******* kid pulls up to be I can take him....all things considered of course!....I have a great write up, so I guess I should just follow that first

General karthief · May 23, 2018

The best thing to do for a dependable, fun ride is to grab a set of aluminum heads, a explorer intake, 1.7 rocker arms your tb and maf and ride it.

justin82 · May 23, 2018

is that your set up?
