Hi,
In 1989 i bought a corvette C1 . This car got a 327 chevelle engine with his powerglide automatic gearbox.
This year i decided to put an original 283 ci engine.
Here is my problem : i would like to mount the powerglide gearbox with the 283 engine.
In 1960 the starter was mounted with 3 front bolts.
My engine doesn't have this mount system , neither the gearbox ....
i only have the same mount system as the chevelle engine but the starter engine doesn't fit ( bolts too wide)
Is there a system (adapter) in such way that i can assemble the engine with the gearbox and the starter?
thanks.
The engine : casting 3756519
102552 TI06CU
gearbox : Casting T8S14N

Are you using the same starter and flex plate (flywheel) used on the 327? Should be a 153 tooth flex plate with the straight starter nosing which bolts to the block.
It has been years since I installed a power glide, but I think that is right.
yes it is a 153 thooth flex plate but what is the solution for the starter engine ? the 327 starter doesn't fit : 2,75 inches on the block and 3,35 on the starter ( between the 2 bolts)
Corvette powerglide transmissions from 1953 to 1961 were the cast iron version. The aluminum powerglide in a Corvette started in 1962.
With the cast iron powerglide you also use the powerglide adapter plate, which contains the starter mounting bosses (three bolts, forward facing).
The bell housings used on Corvettes (and other Chevrolets) up to 1961 also had the starter mounting bosses.
It looks to me like you have a 62 and later powerglide, which would normally be used with a 62 and later style starter that bolts up to the block
with bolts coming up from the bottom.
You are mixing and matching parts between the engine and the transmission, you will need to find a starter that also matches your setup.
Did you try going to a parts store and see the difference in a 283 for your engine and a 327? According to my parts manual there are several different starters for those engines.
hi ,
you are right !
i'm trying to connect a 283 ci engine ( 1960) with a powerglide aluminium gearbox ( 1968) .
it seems to be the same dimension.
The problem is the starter : 1960 engine has the starter engine mounted with front bolts.
1968 engine has rhe starter engine mounted with vertical bolts.
my engine has the verical bolts but the widness ( distance between the bolts) is smaller than the 327 engine ...
the solution would be : or find a starter engine with 2,75 inches center to center bolts.
or find an adaptator plate that permit to adapt the starter engine with the front bolts...;
Somebody can help ?

yes i did try going to ecklers, zip corvette and central corvette .
before 1962, you get a starter engine with front bolts , after 1962 you get a starter engine with verticals bolt but the distance between the 2 bolts is too large.....

If you aren't opposed to using an aftermarket mini-starter, doing so will likely solve the bolt hole spacing problem. Such starters have dual patterns for working with different diameter ring gears.
I think 1960 TurboGlide engines used a block mounted starter along with a uniquely machined pilot hole in the crankshaft for the torque converter ?
That is correct.
The down side of this combination (if there was a down side), is that IF the engine was to be used with a manual transmission, finding a readily available pilot bushing is difficult, if not impossible. It would simply be easier to swap in a crankshaft for a manual or Powerglide transmission.

Do you suspect the OP has a TurboGlide engine?
So, if the pilot in the OP's crankshaft is oversize as suspected, what will pilot the torque converter on the smaller PG converter? Don't know, Just a thought.
PS. A long time ago, someone was selling special TG pilot bearings to convert standard crankshafts. Might have been NAPA?
HI,
I do apologize this will not fit if the with is 2.75, I am afraid we do not have a starter with this narrow of a pattern

Someone that has a list handy can see what engine code a 283 is with a CU stamp pad.
Here's what I found. Would be for passenger car usage.
CU 1958 283 270 8 (dual quads) m/t, 3sp, hi lift cam
It's also listed for Corvette in 58, but the poster has a Tonawanda block, designated by the letter "T" in the assembly stamping, so it cannot be a Corvette block...
