365 Engine Info

What is the correct carby for my 365 engine and what is the outside diameter of the ring gear, is it the same as that for a T700 tranny on a SBC engine

I want to install a T700R4 tranny behind this Cadillac engine...

[Carnut]

Sorry, I do not know the answer, but what you refer to as "ring gear" is called the flex plate here in the USA. In 1957 the carburetor was a Rochester 4 BBL Model 7015701.

What is the correct carby for my 365 engine

Russ

What year is your 365?   

If 56, engine unit number will start with:
4X - Series 62, 60S or 75 w/o ac, w/o dual carbs,
4XK Series 62, 60S or 75, w/ac, w/o dual carbs,
5X Series 86 CC w/o ac, w/o dual carbs,
5XK Series 86 CC w/ac, w/o dual carbs
7X Series 62, 60S w/dual carbs w/o ac or
7XK Series 62, 60S w/dual carbs w/ac

If it is a 57, engine numbers will run similar to 58 on this list in link below but first digit will be a 7 instead of 8.

So far I now know that it comes with a 4 barrel intake manifold and attached is a pic of the rear of the engine with a couple of numbers.
Is this any help...

If you are want to convert to a sbc, it requires modifications to fit the existing transmission.  If you are wanting to change transmissions, then it requires modifications.  There are are no real interchanges except within Cadillac.  But with a beer in one hand and a blow torch in the other and lots of money - anything can be made to fit.

Boy that was helpful advice....

i don't have the original tranny anymore or i'd measure the starter ring for you. i'm using one of these adapters to mate a chevy tranny to my 365. the starter you find at any auto parts house.

Thanks for the info, I have emailed Wilcap, lets see what they have got.

[Denrep]

1956-up Hydramatic ring-gear  measures approximately 14.75" OD, by tape measure.

Bendsten's also sells a kit:

I like that the Bendsten kit uses a common stock GM flexplate (flywheel) and a rugged and cheap GM-type vertical bolt starter motor.

Yes, I owe Bendstens a plug. I hired Bendsten's for some one-off custom work and found them to be extremely knowledgeable and courteous, providing extensive follow-through on working out details which were above and beyond their part of the project.

Good Luck

[fiftyv8]

Thankyou for your flywheel info and reference to Bendtsen's.

Good news is the previous owner of the engine contacted me to say they had discovered the original carby in a box during a shop clean up and now it's mine when I can go get it.

[Gary]

Have you looked at this :

Gary

[fiftyv8]

No, never saw this before, thanks for the link, any idea of cost???

[Gary]

Yeah, I've got a REAL good idea of the cost as it came from my bank account.
The adapter is $795 and the shifter arm was like $45.
The driveshaft was $150.
Trans, installatiion cost will depend on your local shop.

Gary

[fiftyv8]

Thanks Gary, I can install it all myself so just the adapter kit and drive shaft work will be required.
Since Wilcap have not replied to my email, I will contact Bendstens.
I am sure someone will be willing to lighten my wallet.

[flatbroke]

havent been here for ages. my '57 365 had the original (edit>)rochester carb on it.
after much pain, we got a holley on there now.
still got my old one if you get stuck russell...
