    Drivetrain Which First Gear To Go With?

    Did some work on the 1969 Mach 1 this Saturday in preparation for the Devereaux/Kaiser Car Show in Sarasota, Fl on April 28th, 2024 (highly recommend this show). Verified TDC on the balancer....indeed the outer ring shifted from stock by about 10 degrees. Then marked the tick marks with white...

    Rear Thumping Sound

    try to get a video with audio.....but that sounds like a flat spot or bubble in the tire ....I've had that happen to me on all 4 corners as the car sits in the garage for long periods and when it did happen to me the tires were pretty old. If it were bearings I would think it would sound like a...

    Drivetrain Which First Gear To Go With?

    @FastDriver thank you so much for your time. I am no longer sure what year the T5 is ....on one receipt from the transmission shop that rebuilt it in 2012 wrote down 1990. On other receipts I wrote down 1990 on one and 1993 on another....ugh. I've reached out to the guy I bought it from in...

    @FastDriver Some MPH numbers with my current setup of a T5 and 3.00:1 rear....Assuming I have an 18 tooth speedo cable gear. (I found my receipt from Modern Driveline for the 18 tooth gear) I am so sorry I made a mistake in the tire size ...they are actually currently 215/60R14 not 225 The...

    Drivetrain Which First Gear To Go With?

    Thank you for your time. Even at age 59 I can learn things and do frequently....most helpful I believe I changed my speedo gear to an 18tooth when I put the T5 in ....I have to get gas for the old girl...I 'll compare the iphone's GPS and see what the MPH is reading on the dash at 45mph on the...

    Drivetrain Which First Gear To Go With?

    Well damn he had some nice cars!!!! can't get much better than those two. that's kind of the goal.....beating a the mini-van was just for added bonus. I KNOW my 350z whips my Mach 1's ass and gets DOUBLE MPG. Yeah the fact that I don't have to run friction modifiers with the true-trac and the...

    Drivetrain Which First Gear To Go With?

    re: Speedo Drive Gear - oh ...eeks that will be a lot of teeth on the speedo cable's gear to compensate Yes trying to keep it original. And yes I will be going with an Eaton TrueTrac helical-gear style, limited-slip differential. I'll be storing the original open diff along with the...

    Drivetrain Which First Gear To Go With?

    Off the line launch ability. Comfortable highway cruising RPM Beating a Mini-van off the light :) Those are my priorities.... I will definitely go back to the 225/70r14 tires in the near future RWHP of a stock 351w 4v seems to be about 175 if you're lucky (I suspect I'm not lucky ) I think...

    Drivetrain Which First Gear To Go With?

    :-)....so what do you think? 3.25, 3.50, 3.70 or 3.75 given that I have a 1990 T5 with a 3.35 1st gear. note: my 351w 4v is stock with a .030 oversized rebuild in 1989. so very low on actual HP at the rear wheels.

    Drivetrain Which First Gear To Go With?

    I don't want to hijack this thread, but basically better 0-60 times , something that can beat a Honda Odyssey(super embarrassing) from 0-60 ...not looking for low 1/4 mile speed or high top end....it's a stock show car. Based on my calculations I'd be at 20mph at 3000 rpm in first gear with...

    Drivetrain Which First Gear To Go With?

    Well you guys seem to know what you are talking about....would you be so kind as to look at my post and make suggestions? I am not in your league, but would love to hear what you all think. based on my T5 first gear being 3.35:1, I think the 3.70 or 3.75 rear gear ratio would be too much...

    WOW, it's about 20 years !!!!!!. To date I haven't done any of things I mentioned except put in a T5 and absolutely love it. The autolite 4300 needs some help...I have a bad bog when I punch the throttle....which I assume it a lean bog. This year I WILL be getting a new center section with an...

    Suggestions for rear diff gears - 1969 Mach 351W 4v

    My Mach 1 was born with a 3spd TopLoader and 3.00:1 open diff (not going to lie ...that combo sucked) A while back I swapped in a 1993 or so Tremec T5 (I love it BTW) , but the performance is still pretty low....so this year I am going to get a whole complete center section for my 9" rear...

    How to remove door windows, 1969 mach1?

    "...it will fall out on its own" LOL - no doubt eventually it will, always had. I'll probably buy the parts needed , store them and wait until the day it falls out again. Was just wondering if there was a way to hurry the process along. Are the earlier models done the same way? were other...

    How to remove door windows, 1969 mach1?

    Ok folks, thinking ahead of things I want to do and want help in doing it right without ruining the paint. I have had problems for years with my passenger side door window coming out of its channel, and have re-glued it with various glues. The one that seems to be working so far is an Elmer's...
