Re: Transmission ID

What are the numbers on the metal tag?
The tag is rivted to the side of the case at the very front. Passenger side.

The casting # on the the trans in my R code Mach1 is C8AR-7006-D
You listed the casting number for the tail shaft housing. It matches mine

I found a rectangular tag. I'm estimating it's 3/4" x 2". It was halfway
up on the passenger side. The 2" side was horizontal. I cleaned it off,
and I can't read a thing! There are no raised or sunk letters, so a pencil
rubbing will not yield anything.

Any ideas?

Re: Transmission ID

MAJOR distraction last weekend and this week. An internal job posted in my
company that I'd love to have AND it's in North Carolina! If you didn't
know, I come from North Carolina and that's where all our family is, soooooo
I got excited, the wife got excited, and MAJOR distraction! I applied, so
let's see what happens.

Anyway, I'll determine this weekend if it's really a close or wide ratio.

Cary.

That would put you in High Point, right?

OK, she's up on four jack stands and in 1st gear. Going by eyeball, I taped
a vertical line of 1/2" masking tape from the quarter panel to the floor
that sights dead on with the center of the rear wheel when viewed straight
on. I taped the floor where I stood. I put the engine at TDC and marked
the top of the tire with more masking tape that lines up with the vertical
line. I turned the engine until the tire went 1/2 a revolution, i.e.
masking tape at bottom and hidden by vertical line when sighted straight on.
The timing pulley lacked 3-3/8" of circumference being 5 whole revolutions.
The pulley measured 6-1/2" diameter. So, 1 revolution of the rear tire
would have taken:

2 x [5 - 3.375/(6.5 x 3.1416)] = 9.67 revolutions of the engine.

Previously, I established the rearend is a 3.50:1.

9.67/3.50 = 2.76

1st gear in a wide ratio is 2.78:1 and in a close ratio is 2.32:1. It's a
wide ratio toploader.

The 3.50 rearend with a wide ratio toploader is equivalent to a 4.19:1 with
a close ratio toploader. No wonder it's so damn quick off the line! ;^)

Your logic is sound my man! Well, I -was- looking over your shoulder,
you know, like before. =) "Click... click..."

I definitely need more cam for my gears - the Tremec has a 3.27 first
and I run 3.80 gears. It's like a damned tractor; I can just let the
clutch out at idle, and it won't stall. It is good in traffic with a
bunch of automatic drivers. I either use 2nd, or I have to take 1st to
3500 or so. It leaves nice and hard even with the inferior motor.

Fast Ed did recommend some tires that made a world of difference, though
(Firestone Indy 500s, 215/70-14 F, 235/60-14 R). CJ and others said
this was a common combo back in the day - F70-14 and G60-14. I just
have to run the rears at 28 psi so I have a good contact patch.

My Cooper Cobras looked good, but just howled and spun. They absolutely
SUCKED when I got caught in the rain. And I could chirp 3rd with about
100 lbs./ft. less torque at the flywheel than you have
