3955582 block behind water pump
11 205 cfd block by dist
#8 on intake by 1 plug
22503087 on intake manifold
please help thanks

Chrisg256

im wanting to put in a 1970 cutlass S, id like to also know what would b a good intake to get for street use

Mikes442

It is either a 68 or 69 350. The manifold was in 68-69.

Chrisg256

found a W or M under intake, also found a 17 behing waterpump intlet

Try looking at the machined VIN pad above the #1 cylinder on the block. It will have the year of manufacture in the string of numbers.

As for an intake manifold for street use, that kinda depends upon rest of the engine setup: compression ratio, cam, etc. A factory iron intake, factory aluminum, Edelbrock Performer 350, or Edelbrock Performer RPM could work.

didn't c any numbers on block, may not no what im looking for. found these on the heads 411 338 14
exhaust 14 22503678

You mentioned it had a #8 near the number one spark plug. That's the head casting number. The #8 heads started in 1973 and were used for several years. Check the vin as others have mentioned, that will tell you what it came in. But many of the parts you'll buy for it will interchange from 1968 through I believe 1977, about then some items changed such as the valve cover gaskets. John

It is either a 68 or 69 350. The manifold was in 68-69.
====================
What?
No.
That intake is a late smogger #17 casting
After 1976 I believe.

The block is 68-76
The heads, large #8, are 1973-1976 only, casting number 411929 if you "look more closlier"
[South Park ref.]

Find your VIN stamp on the block per above.
Find your Engine Unit Number stamped into the oil fill tube- it's 3xxxxxx for 1973, 6xxxxxx for 1976, etc.

Interesting that the block "year" [mold #?] is "11" - which kind of shoots the Calendar Year thing down- so 1967=1... 11 would be 1977, during which no 395558-2 blocks were made as far as I know. On to the 3B block by then. Got a photo of this "11"?

#14 xst manifold generally goes with the #17 RH manifold and are again post-76 era parts.

You have a mishmash of stuff. Which brings up hey maybe you have that rare water pump, pulley, distributor, carb, etc.

PS if you have Excel, you can use my PN database
ctrl-f for find
enter your PN or portion thereof
voila', all we know about it.

I do have excel

This:

P1010401-1.jpg

P5060220.jpg

The second number is the year of manufacture.

Chrisg256

does this look right
G50483811
that dimple looks like a could be a G

Actually 1 is for 1964. A cast in 1967 block would have a 4 next to the dissy hole. It has nothing to do with mold number, its a year desigination number.

His block being an 11 means it was cast in 1974.

The VIN derivative stamp should be nine characters. If the motor came out of an Oldsmobile, the first character will be a "3". It will always be a number, not a letter. The second character will be a digit for the year. If it's a "5", that would signify the 1975 model year (which would also be consistent with the number 8 heads). The third character should be a letter for the assembly plant. The last six characters are just the last six digits of the VIN from the car that motor was installed in at the factory.

Keep in mind that year of the BLOCK alone does not tell you what parts you need. If you have a frankenmotor that's been cobbled together, you don't really know what parts to get without understanding the entire picture. Sorry.

Chrisg256

so if the G is a 3, the it would be a 75, would all the numbers make sence

Block 395558 2 (68-76 )
#8 heads
Intake 22503087 ( 73-76 )
Exhaust 22503678 #14 #17 ( ? )

so can we assume it a 1975?

joe_padavano

If the first two characters of the block VIN derivative are "35", then you don't have to assume anything. This is proof the block is from the 1975 model year. Of course, that's all it proves. There are no similar VIN derivatives on the heads, intake, or other engine parts.
