engine ?

[67c-20]

i have an engine i am trying to id. i have been to a site that tells me the suffix code id but there are 3 different choices. i do not have the vin and i have no idea what it is out of. i have the code from the front of the engine block it is TO5ZIGF. i am sure it is a 283. my other ? is there a difference between the turboglide transmission and the turbo 350?

(difference between the turboglide transmission and the turbo 350?)......as far as the tranny question,,,,,,,,do you mean "powerglide"?....its a 2speed tranny, low and drive,,,

There is a big difference between the Powerglide and TH350...the PG has two gears and the 350 has three. I have a similar code on my 283, TO526GF, and I could not find it in the traditional engine code files but I know it is a 283. It is likely mated to a powerglide since that was the auto tranny available at the time.

67c-20
It looks as though it was manufactured at the Towanda im the month of May.
The other data is like you stated in your post:
1955 GF 265 m/t, 3 spd, a/c
1957 GF 283 turglide FI car
1965 GF 283 Powerglide 195 2 full size

You might want to try and find some more numbers off of the block or heads, maybe a casting clock would help to narrow it down a little more.
I am leaning a little more towards the 65 model because of the 05 in the code you supplied

I have not heard of turboglide though it possibly could be a powerglide, I heard about an aluminum p/g but I am by no means an expert. they could have all been the same fo what I know.

Have fun

every powerglide i have seen has powerglide written on the top of the case.the one that is hooked to this engine does not and it looks like a th 350. i have never heard of a turboglide but i thought i would ask. what other casting numbers would be helpfull. the clock is pointed at the 10 o'clock position. it has a 2 barrel on it now that is was i was leaning toward the 65 model as well. could turboglide be a speacial name they had for the fi engine in 57.

Hutch, Thanks...I just figured mine out and see that you posted the good details!

67c20....my engine may have been built five days after yours...it is much fresher...LOL...wanna race? With my luck...mine was built in 1955. Considering the looks of it has to be at least that old. I just did a compression check on mine and it still has between 145 and 160 psi! It sat under a tree in Sandy, OR for six years before I got it! It's a survivor!

Chevrolet made Turboglide Transmissions in 1957 & 1958. They
all failed very quickly. As far as I know the factory replaced all of them with powerglides. You can tell a motor that had a Turboglide behind it originaly because the pilot bushing hole in the end of the crankshaft is bored slightly oversize. Bushing will fall out when converting to stick. We used to wrap a dog food can around them & hammer them in. Very unscienetific. Trans selector on column had Park-Reverse-neutral-Drive & Gr. (Grade) on it.
Transmission did not shift.

67c20, "05" is May and "21" is the day. Hutch is right that the casting code will give the year of the casting. Evidently there is no year designation for assembly, plant, month day and tranny configuration. If you look closely you will find that your ZI is really a 21.

Did a quick search on the turboglide they were introduced in 57 and were last installed in 61.
So it is looking more like the 57 car all the time.
Single speed
Maybe the fuel injection part was removed or something else?
Pontiacs used the 283 turboglide combination also:

Here is some info:

Pontiac's Startling New Turboglide;

For 1957, Pontiac introduces the greatest new contribution to automatic driving in years! This great all-new automatic drive puts three turbines to work to provide the smoothest flow of power ever experienced in any car. And for greater safety, Turboglide introduces a variable-pitch starter and Hill Retarder to the low-price field. With an infinitely variable torque ratio from standstill to cruising speed, you experience an unbroken flow of power without the slightest hint of a shift. A single forward drive range provides flashing triple-turbine acceleration… extraordinary power for hill climbing… Turboglide's silken-smooth normal cruising… or fluid-smooth deceleration. With Turboglide's amazing new “Hill Retarder” a flick of the lever eases you safely down the steepest grades. All this is achieved with less weight, fewer parts and simpler controls

Never heard of a turbo glide before.....looks like a cool tranny though.

So it has a constant variable gear ratio with no gears? That would vastly improve acceleration.....too bad it failed
