TH350-VS-Powerglide

I am swaping the trans in my c-10 I have th350 and a powerglide. My truck has a 230ci inline and 4.10 gears. For the sake of driveability what should I put in it.

 

A heavy vehicle with limited power can always benefit with an extra gear. Also a turbo 350 has a lower first gear too boot.

 

Huh!?
You're still 1:1 in high gear.

 

I think we've pretty much got a no-brainer there

 

both are good transmissions and i have used both in projects. while both have 1:1 high gear , the two speed power glide will have either a 1.76 or 1.82 low. the tree speed th350 will have i believe a 2.52 low and a 1.52 second

the extra gearing of the th350 may help get your somewhat heavy pickup with a low powered motor going better. a 4 speed overdrive 700r4 with even lower first gear would be ideal with your 4.10 rear gears

 

I agree with you 3-window on the 700r4 Im just trying to stay on the cheap for right now and I have these trans just layin around.

 

the glide needs a bell crank to work correctly
I.e. pain in the ass
also its a pain in the ass to hook up a locar shifter
th350
tk

 

Not sure about the bell crank, I have a Pg in my car, but that being said if I had to do it over and had access to a 350 I'd run the 350 for the extra frist gear.


I have a gennie shifter in my PG and it was a snap to install.

 

do you have a crossmember for it?

 

Glides are good 1/8 mile track transmissions, the 350 is a good strong unit but the 700 is nice due to the 15% overdrive and lockup torque converter

 

if you already have the TH350..i would use it

 

More gear splits can get an underpowered vehicle moving easier. That's why semi trucks can have as many as 21.

 

Yea I found a cross member in junk tard off a 67 truck. I had a guy offer me one for free from a car but I dident think it would work. I have to admit I am kinda dumm to trans stuff.

 

Also if I remember right the trans lengths might be the same between the two but the yoke
splines are different.

 

th350s are awesome cheap parts =s more fun shift kit 30 bux shifters dime a dozen converters are cheap

 

Th350

 

you can make a 350 churp second everytime for no $, remove the accumulator spring for second gear. It's behind the round cover on the right side. Its done all the time.

 

For a lightweight car I think you would enjoy the glide combo with those 4:10 gears. My 69 camaro I had was very light weight, all stock with a 6 and glide with mid 3 gears in the rear. It ran very nice around town but when I swapped out to a 350/350 combo I somewhat lost that low rpm scoot.

6's are low rpm torque motors so a glide kinda smoothes out the role from a start and it takes way less horspower to spin a glide than a 350 and 700r4.

I don know about the use of a glide in a c10 unless you have 4:88's in the rear -its too heavy of a vehicle.

 

700 has a 30 percent overdrive.

 

I swapped my PG for a 350 a few years ago, best move I ever made. The mounts, drive shaft, everything basicly swapped over.
