Looking for a website for engine identification.

[jdub]

I want to know the year and specs of the motor I have.

371
388
82

Anyone know where I could find it?

 

[jdub]

Looks like I need more info, back out to the motor.

32 GM 3970010 Is the casting number

 

[Tacoma]

www.mortec.com


3970010....302.....69....4...Z-28 Camaro
3970010....327.....69....2...Trucks and industrial
3970010....350...69-80...2 or 4


My guess is that you have a whitebread 350. Any chance you have the head casting numbers???

EDIT: I'm asking because there is no real visual difference between a 327 and a 350...

 

[jdub]

Yeah Tacoma I really couldn't tell. The date isn't where the casting number is so that doesn't help. Where do you find the head casting number? Do I need to pull the valve covers off?

 

[jdub]

I'm either looking to rebuild or sell parts but need to know the spec to do either. It has corvette valve covers.

 

[Tacoma]

if I'm remembering right, the head casting number is under the rockers, so yeah, pull the covers.

You MIGHT have a 327. That would be neat.

MorTec's site is a good resource, but GM used the same numbers for a few different blocks.... knowing the head #'s might help narrow it down, though that's not bulletproof either, with SBC interchange. I don't have my more authoritative books handy, they have all the little distinguishing characteristics.

You may end up having to pull a head and mic'ing the bore.

Are components like intake, headers, and heads transferrable within the SBC category?

Yes from 1955-1986 .. then it gets interesting

Within generations, yeah. Pretty much everything up to... 87? interchanges. In '87 they changed the angle on the center bolts of the centerbolt heads (w/valve cover bolts in the center of the valve cover), but you can use earlier manifolds if you hog out the bolt holes... And then they went to Vortec stuff w/different intakes... but those heads will bolt up to eariler blocks, you just need to use the Vortec intakes too.

and the newer stuff is a lot different from the older-style...

Basically each family of engines interchanges with itself pretty well. Most people are used to the 1st-gen style engines.



and for your purposes, things interchange between the 302/327/350.

 

[jdub]

Thank you my chevy professor! You always have the info needed.

That would be neat???

3970010....302.....69....4...Z-28 Camaro

Now, THAT would be neat! (I'm sure you're just too young to know though)

 

[Tacoma]

That would be "a shame" to have that motor sitting in a Jeep.

I AM too young to remember, but not too young to know.

Thats worthy of being quoted
