Thanks Mike!

 

Looks like I have 305 heads. My casting # for my block do not match up with any on that site. I am thinking it may be an olds block because when i puulled the starter off I noticed it looked like the one I put in my dads olds a couple of years ago. One bolt longer than the other kinda offset. I am not happy....:cry:

Many chevy engine starters have offset bolts holding the starter. 010 at the end of your block number is a very popular chevy 350 number.

Block:

GM 8970010

 

Could you have misread the 3 as an 8 on the block?

 

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

3970010....327.....69....2...Trucks and industrial

3970010....350...69-80...2 or 4

 

Hmmmm Good point I will look tonite. What are you referring to with ....4

...2? 2 or 4 bolt mains?

On the front of the motor, passenger side, the block deck extends past the cylinder head. GM stamps this part with a block suffix code and a partial VIN number. Post these numbers for further decoding. Note, if your block has been decked, these numbers may be gone. The 3970010 can be either 2 or 4 bolt main, but all are 4" bore. It is a good block and fairly common. In the bellhousing area as well as under the timing cover will be some 2 digit numbers as well, either 10 and 10 or 10 and 20. These are in reference to the amount of tin (1%) or nickel content (1% or 2%,10 or 20) The 20 blocks are high nickel content blocks and are most desirable for wear resistance).
