Question 350 block pre-purchase checklist

Ok, I found a 350 4-bolt locally and I will go see on Mon or Tues. This purchase will be for my car buddy and I as a learning project and to satisfy a goal we both have.

There are two pieces to this post - a checklist and then a question below about mounting blocks to 700R4's.

Based on comments from prior posts I have compiled a list of items to check before I purchase.

1. confirm casting # of 3970014 which seller sent via email
from mortec - 3970014....350...70-76...2 or 4
seller says it came from a 76 Camaro

2. look for 010 or 020 in the timing chain area
see if it is a "high-nickel" content block

3. confirm 2 or 4 bolt
seller says 4 but we don't have pics to confirm

4. main caps present?

5. helicoil in any bolt threads

6. check bore size
need bore gauges and micrometer to check - I don't have
will check and see if I can rent/buy locally

7. crack in the lifter valley
is that visible to the naked eye?

8. visually check cylinder walls for scoring or discoloring

9. check bottom of bores for any internal block damage
look for chunks missing do to rod failure

Did I miss anything? Any suggestions?

Also, the seller says the reason he is selling this block is it won't mate up to his 700R4. I have a 700R4 in my 55 Belair and if/when we get this engine built I would like to replace my 305 that I have today. What's the deal here? Is there an "adapter" that I already have or can purchase to get this block to mount to a 700R4?

--Jeff

Check list looks pretty good.

If a SBC is bolted to your 700 trans, then the new one will too!

Another place to check is around the freeze plugs on the side of the block, sometimes the block cracks there if there was just water in it instead of antifreeze mix.

Check the back of the block for the 010, 020 its sometimes there.

as for the 700R4 if it was a BOP trans or a trans for a 60 degree V6 it won't bolt up to a SBC.

Stoned, hey I sent you a p.m., did you get it? The 010 , 020 numbers on the block, in the timing chain area are what you are looking for!
