Engine Rebuild - strip down

Well, here it is. I bought this a few months ago - it's a small block chevy 350.

It came with a few extras but is missing the carb and a starter motor.

The engine casting number is 10054727 so after a bit of research on the web I found that it was made in Canada and is the one piece rear seal, 1986 upwards

Stamped on the other side of the block were two more identification marks. The first was not very clear and looked like it said CK7/07362 - I think this is engine id number. The second was K0829TPM. The K means it's made in Canada, the 0829 is the month and day, so it was made on the 29th August, and the TPM is the suffix code. Looking at this website and searching for TPM I found out that this engine was made in 1989, was in a chevy truck, had 210 HP and was a TBI engine. The key piece of information here is the age. For the IVA you need to be able to prove the age of the engine, which then dictates the emissions tests they will perform. So for this engine the emissions test will be as follows:

Engine block Date- 1-8-86 to 31-7-95 = Visual & <= 3.5 CO & <= 1200 HC @ normal hot idle. HC can be tested at 2000rpm if CO passes at idle

So having identified the engine it was time to start the strip down. I have never done anything like this before so did a bit of research on youtube. I found this video very helpful.

I also purchased a couple of books:

How to Rebuild Small Block Chevy by David Vizard
Rebuilding the Small Block Chevy by Larry Atherton

Both books go into a lot of details - the second one comes with a DVD which shows the entire rebuild process. As I novice I found the second book easier to use.

I have also been very lucky in that my neighbour is a retired Chief Engineer from the Merchant Navy and he was really keen to help out with the rebuild. This worked out really well as I've learnt things that I'd have never got out of a book.

So we stripped the engine down over a period of about a week. You could actually do the entire strip down in a couple of hours but we took our time and bagged and recorded each bit we took off.








The engine is now at the machine shop. After looking on a number of forums, Dave Rushton came high recommended (http://www.daverushton.co.uk/). 
The engine was dropped of on the weekend and Dave is going to give it a good check over and advise on what work it needs.
