Mark 8 gears and engine mods

Back to the original question. Do the maintanence items first, fluid fushes, spark plugs, wires, etc. Next comes the Jmod, air silencer removal, you already have the exhaust, so your good there. 3:73's or 4:10's seem to be the most popular gear options for our cars, along with track lock. The gears really wake the car up. Do some reading on Tuners from various venders such as SCT, which is what I went with, and couldnt be happier.

That should keep you busy for a while.

k9t8m did try to bring the thread back to the topic

great, i get called helpless from a complete stranger and i get the -1.... not saying hes a bad person, just that if anybody doesnt have something helpful to add to a post why chime in with comments like that ?

Mainly because you are not letting this go now... the issue was addressed and kustomizingkid apologized

actually i live in waco GA.

After the thread went back to discussing Mark VIIIs you're keeping it going.

LvC is basically a self-moderated forum.... when things get off track or negative members tend to bring the threads back or calm things down.

Which has happened in this thread. You will find as you get more accustom to this forum that some of the people that you may think are busting your chops right now will end up becoming your friends.

We all fall to the temptation of immature posting from time to time and allow our frustrations to poorly or wrongly snap back at a member's post which has offended us. (Unless you are in the political forum where that's the boxing ring of the site)

Perfect example for me is my relationship with Fossten or Frogman. Fossten and I have have many unfriendly post in the political section but we still consider each other friends and can have fun or respect each other in the automotive or social forums.

Frogman and I well lets just say I didn't care too much for a moment early on, and we had some bad postings back and forth, but when I got to know him I found out that he was maybe one of the most respectable members on this site and would almost give a left nut to help anyone out... What he did and offered me while out on the road one day last year was more than anyone else would have offered that situation. He's a true man of his word.

So let's move on and leave this issue behind...

Move on and Move Forward.

I think not I love my 3.55s and now I just need more power

what a waste of labor and gear lube.

Going from 307's t0 355 is almost immeasurable.

Hell going from 307's to 373s only made a 300 RPM difference in my cruise RPM.

I couldn't see any reason to change gears unless your actually gonna make a significant change to the ratio, especially considering the cost involved.

If you want to waste YOUR TIME and MONEY on 355's, feel free..

BUT.. please dont post info that will make some newbie think 355's are all that great..

355 is the "weiney gear" they put in the mustangs...

REAL mustangs get 373's..and are often changed out quickly for 410's or 430's.

If you wanna run a Mustang WEENIE gear.. feel free.

355's are for wusses that can handle REAL GEARS.
:eek:
 
actually i live in waco GA.

ahhh my bad.. I didn't think there was a town called Waco other than here in Texas, goes to show. I "aint a know it all"..haha

anyways.. welcome to LVC, dont let our brash/honest comments disuade you.

There's alot of good information around here, and some people who will bend over backwards to help you. {not to be confused with bending over forwards)

You'll see.. "we aint all that bad"..once you get past the gruff grumble.

again.. welcome to LVC
 
Lemme see here...

A guy with the username XLRVIII that actually HAS 373's says they are a waste of time....and effort. and that 410's or 430's are the way to go..

Then a guy with the username slowmkviii says "355's" are better...

...nuff said.
HAHA

How fast has your slow mark gone in the 1/4 slowkmviii?

LoL Tommy,
Not everyone has a strip close.
No one has made more dragstrip passes in a mark then you....no wonder you want 430s
This argument is old and beat into the ground.
Anyone who wants a gear change can do a simple search and read for HOURS then they can decide what is right for them.

'Nut, you are correct..I agree.

I just remember that day and how dissapointed I was when I put the cobra center section in.. the job itself was easy.

It was one and a half hours from the time we put the car on the lift until it broke the beams on it's way to it's "first pass" on gears.

I only hope to keep someone else from spending a healthy sum of money and not getting the "bang for the buck" they might have been seeking.

.. i know I didn't.
 
Well the The Super Mark has 355's in it..

with 100-150 more HP I'd consider running less gear...

if I were going to turbo charge the car I would probably consider putting a traklok on a set of 307's.

But for a first entry level mod for a mark 8.. DO NOT FEAR THE GEAR as has been said 100's of times.

410's min for NA street duty with 430's being the optimum choice in my opinion.

If you have a 307 non lsc turn your overdrive off while you are on the freeway.
That is almost exact rpm's that 410s would be with overdrive turned on.

If you have a 327 LSC do the same, that is almost dead nuts the same as 430 gears.

Try it and get back to me.
 
I have not run my car with the gears and I do a lot of freeway driving The

3.55s just make the car feel better and I get better gas mileage when around

town. I have also driven a t-bird w/3.27s with no O/D it bugs me to many rpm

for me. I did want 3.73s but the diff came with the 3.55s and didn't have the

money to invest in new gears.

Also is the 3 tenths or so from 4.10s worth the loss of 10mpg or so on the

freeway

I dont know WHAT you are smoking, but I sure wish you would send me some!

So from what you said.. your choice to run 3.55's wasn't an educated nor informed choice, but rather you couldn't afford a real set of gears.

So rather than speaking from experience, your just speaking from a point of "simple economics"?.

Now with that said...

my car has 373's, my girlfriends car has stock gears...

our Fuel mileage is within ONE TENTH OF A GALLON from her car to mine.
There is NO way that 410's are going to DROP 10MPG over stock gears UNLESS you run around with your gas pedel welded to the floorboard.

and I will make the same challenge/offer that I have made atleast 20 times in the last 10 years.

IF the ORIGINAL poster puts 410 gears in his car and determines that "it's too much gear" I will TRADE them my 373 cobra center section for their 410 center section.

and to SLOWMARK, if you think I got to over 400,000 miles without ALOT of freeway driving..then again, I really wish you would send me what you are smoking!
 
I drive the car on the highway A LOT and 4:10's were completely out of the question for me. Yes they would have worked fine, but I dont want my car running at that high of RPM on the highway.

For me 3:73's were a great choice.
 
that's odd, because the final drive rpm difference is only like 200-300RPM between 373's an 410's
 
at 80mph your lookin at 2600 with 373's vs a littler over 3k with the 4.10's
 
plan ahead with your mods... they have to compliment each other and correlate. I say start off with a tune first.
 
If I ever do a set of gears, I will not do anything less than a 4.10's as anything less just doesn't seem to be worth it IMO. If you are worried about freeway driving then I would just leave the stock gears alone & be happy.
 
Not an educated nor informed choice you say first off I wanted 3.73s and got 3.55s instead cause they were a great deal it was educated I didn’t want 4.10s ever I don’t like how they drive every day and I like to cruse at over 100mph some times

As for mpg loss w/3.27s I averaged 28.9 from prior lake, Mn to cedar falls, Iowa doing and average of 75mph and 4 runs down the track lets see 4.10s do that

And for trading you gears you can trade with Markviiiedrea he no longer wants his 4.10s

Unlike you I want people to know there is more than just 4.10s that can make them happy.

Then you said “that's odd, because the final drive rpm difference is only like 200-300RPM between 373's an 410's” the why didn’t you go with 4.10s was your choice uneducated nor informed.

I never said you don’t drive on the freeway just that I don’t want to be running almost 3k rpm on the road all the time

Now after having the gears for a few months I think they will be great with another 100hp or so I think down the line I don’t want a 14sec mark I would like 13s and to be very drivable

And this of course is all IMO you know the thing people are allowed to have

you went from 327's to 355's?

that has got to be the most worthless gear swap I ever heard of.

I thought you'd atleast went from 307's to 355's.


and like I said, so long as someone doesnt come along and take your advice and think they are going to get ANY measurable performance increase..

you would probably make "more of a gear change" going from 225-60-16's to 245-50-16's than you did with your 327 to 355 swap.
 
I didn't say someone had to by 3.55s I'm just saying that i like them and you don't have to go with the crowd
If anyone wants to drive my car before they make the choice come see me

I thought you'd at least want from 307's to 355's.

Moving up one gear set isn't necessarily worthless. It really does depend on what you want out of it. I'm considering moving up from 4.10's in my truck to 4.30's or 4.56's... mainly because I'd like just a touch more RPM on the highway so it will tow a bit better. I don't need a huge change as running my 33" tires over my 35" tires give me all the difference in towing I'm looking for. My main draw to the 4.56's right now is price; they are much more common and there for cost less... and when you're doing it... X2, saving $100ea, or $200 total... it's a size-able difference. But, I've got some engine work coming up and I'm waiting to do that before I do any gear changing; see what happens.

I've driven a mustang with 4.10's and an AODE; it's a beast from the line, but not what I'd really want to cruise down the highway for 300 miles in. It was a bit better with the 3.73's, more tolerable. Of course, he's now swapped in a T-5 which has a much lower over-all ratio; I'm not sure how much first gear he has anymore!

Anyhow, if you're more of a straight line person, or don't mind high RPM's on the highway... go 4.10's

If your priority isn't the strip and you want more reasonable RPM's... 3.55's or 3.73's... or 3.90's
 
And for trading you gears you can trade with Markviiiedrea he no longer wants his 4.10s

He cant trade :) I have them :D

To each there own just read and be informed and then you can decide.

slowmkviii you did what you wanted to someone else will decide something different.
Just know what you want to do with the car then the choice then is EASY. :cool:
