Cruising @ 3000rpm's on 4.10's

[76 Maverick]

Love my 4.10s.....also love my OD!

Did you take advice from someone here on the board? Seems like 4.10's were always the "way to go"...and that "don't fear the gear" bullshit. It's a little different in the real world of driving on the street.

No,
just drove my new set up for the first time on the Hwy and felt
out of gear @ 3k, I guess I need track seat time.

Is that a p71?

[mustangguy289]

When I cruise in mine I am turning 3300 RPM to go 60 MPH. 4.30 gear with 26" tire.


I want a built AOD so bad.

Nope

Yea , you're cruising at about 50-53 mph. Sucks if
You try to go anywhere on the highways and damn near get run over. And since all the tracks are 40-70 miles from my house , I went to 355's, much better. 3300 on 28,s = 70mph

3200 Rpm, 1:1 final trans gear, 4.10:1 rear, and 28" tire =64.98 mph for the OP.

3300 rpm, 1:1 final gear, 3.55:1 rear, and 28" tire= 77.39 mph for you.

Wat ?

a glide is a 2sp

do the math

buddy of mine ran a 2000lb turbo pinto with a C4 and only ran 2 gears through the 1/4

[Johnc]

Is 3rd gear in a c4 1:1?

guess so since it doesnt have over drive. :P

W/ a powerglide it would be closer to taking off in second and hitting third.

1.76 first in a PG versus 2.46 in a C4. Maybe I misunderstand what you mean.

gear the car to run 1st and 2nd only. don't shift into 3rd. 3rd is your cruising gear

you have to be spot on with the converter, but I know somebody who has done it. it was in a really light turbo car though

You probably have a righter converter

What gear was he running ?

[mustangguy289]

You probably have a righter converter

That is just the simple math assuming no slippage.

2.3 turbo carb methanol

high 9 sec car

2.3 turbos don't work......
