The Stovebolt Site Forums The Shop Area Engine Shop Trying to identify engine and carburators

Hi Y'all

I got a "new" Chevy 52 3600 I know that the engine is newer than the truck. The ID which I found on the engine a straight 6
goes like this.

Also trying to Identify a Carburtor. Pictures of both located here (I hope)

Hy Savannah54, welcome, you're correct, the engine is from 1963 or newer, could be a 194, 230, or 250. Are there any numbers stamped into the machined pad behind the distributor? The carburetor is a Rochestor model "B" which looks like it is an older version than the engine would have had on it from the factory, hope that helps

Thanks SS
Thanks for replying No numbers stamped around the distributor. I'm just trying to figure this when lookin' for parts

Julian,his handle is "3B". "Shop Shark" is the title given to members with more than 500? posts. 3B is correct on both your engine,and carburetor. i had the same stamping on a '62 Chevy C-40 bus. It didn't have any numbers by the dist.,either. Found out that it's a 250. Welcome to the '"Bolt"!

Thanks 3B and wetwilly I'll see where I can go with your info.

According to Leo Santucci's Inline Six power manual, your block is a '68-'88. The location of the dipstick tells this much. With out a number stamp to identify it, next option is to check the stroke. Pull one spark plug out and stick a long narrow stick down the hole and rotate the engine slowly till the piston hits bottom. A 230 ci has 3.250" stroke, the 250 has a 3.530" stroke, a good 1/4" longer. The 194 went out of production in 1967 so I would rule that out.

Thanks Joe, I have Santucci's manual I had not read farther than the first chapter. Where did you find the reference to the dipstick location.

Also having a GM engine in a chev. truck dosen't look so odd after reading this manual. So was General Moters the parent company to Chevy and GM

Easy way to tell a 230 from a 250 is that a 230 has flat top pistons and a 250 has dished.

General Motors is the parent company to GMC Trucks, Cadillac, Chevrolet, Buick, Pontiac, Oldsmobile, Saturn, & Hummer. In the early years most divisions had their own engines but shared engines for trucks. Most later vehicles had Corporate (Chevrolet) engines.

Thanks everybody,
So far I've found the numbers were incorrect as posted in the first posting.

00N2 C112

So I updated the Month and date to C112 this means that I have a engine made in March on the 11 of 1962. I believe the Pistons are flat top.

Thanks everybody for helping me find my way!!

I was looking on page 21 of Leo's book, top photo. I think I have the second printing of the book.

I found the ID next to the distributor F0417CBT

From what I can find, it looks like its a 1970 or newer, the engine codes switched to three letters at that time. The C112 could be 1972. Look on the head for a casting date, it might be under the valve cover, that might help.

F -- Flint plant
04-- April
17-- Day
CBT-- engine code

Ok Numbers on the head onder the valve cover. From left to right.

12 GM 26 D82 084X 2962084X

Numbers on head on left side

45 F 2086 2084

D - Apr, 8 - day of month, 2 - '72, matches the block code of 04-17.

Joe

You just have to love casting codes. I have yet to make much sense from them. But on a lighter note, What week in '72 had 8 days?

Great, I'd like to thank everyone for your help in identifying my engine.

That was a special week, only one ever!

Joe

Leap year!
