521

[Jason521]

Looking for a 5 speed tranny for my 521. As well as a new radiator.

So much for asking which slave cylinder you should buy!!!!

[DanielC]

I have a long tail z car transmission in one of my 521 trucks.  Used the original 521 slave cylinder.

[Jason521]

Haha I know. But I just got my tax return and I have neglected my poor truck. I would love to swap to a 5 speed so I feel comfortable taking it on the highway and not revving out.

look for a short tail 5 sp from a 720 and put your bell on it and u will have a stcok length 5sp...its what my 521 is

[DanielC]

I believe the original 521 four speed did not have a removable bell housing.

[jrock4224]

your right i forgot i cananbalized a 620 5sp fr the bell...and that's how i got a bolt in 5 sp.... ALl others have a little work and a drive line to make ... mine i made a new mount and put it n...

Even with the 4-speed you'll run out of horsepower before you run out of RPMs.  Unless your engine is built up well over 125HP.  5-speed won't help that.  I ran cross-state (dang near 300 miles) doing 75-80 with the same rear gears and a 4-speed.

 

Unless you're running dinky tires, I suppose.

 

Lack of a 5-speed shouldn't be anyone's excuse for not going out on the highway.  These engines LIKE to rev.  They aren't GM V-8s. 

 

It's gonna be loud.  It's called lack of sound deadening.  You want to hear loud, should hear my '84 CUCV (Military Chevy) with 4.56s, no overdrive, 6.2L Diesel on the freeway.

 

Drive the thing, save up to do a proper swap and gather the RIGHT parts, but don't worry about it.  Rushing to get parts cause you have funds now, just means you'll pay more.  Wait for deals.  When you HAVE to pull the transmission for a clutch, do the swap then.  I've got all the parts to do the swap in my 620, but I'm not gonna even bother until the clutch goes.  Which may be a while, as I've gotten 100,000+ on a clutch that was slipping when I bought the car... and the 620 one feels solid as a rock.

Tranny mount ..... I have a l 16 with a 5 sp everyone hated on my plan but in drive it daily and plan for hills .....lol

[Jason521]

Awesome thanks for the info. I was always scared about revving it out. I do have small tires on it. On a set of 95 pathfinder wheels. But... i will just fix the slave cylinder and take her out again!
