[DeTomaso] [SCPOCA] The continuing saga of...

[Will Kooiman]

No way on the belts.  You would have to put some serious hurt on the belts
to trash a bearing.

 

I would lean towards using your other block.  You could spend as much on
this block making it right as it would cost to do another block - and then
you still might not trust this block.  Who knows, maybe the block had issues
all along and that's why it spun.

 

Another idea is to get a second opinion from another machine shop - instead
of from us wannabes.

 

If you keep that block, I might try boring more and machining a spacer.

my engine.

 

A 4 bolt replacement cap from Will fit well and the block was line bored
again. 

Everything cleaned up except the block web on both sides where the cap mates
with the block.

Driver's side is a little over .001".

Passenger side is .004".

75% of the bearing surface is good... those areas aren't.

 

My choices:

 

1) Run it like it is...  (maybe in Granny's old Ford...)

 

2) Line bore it some more, but it'd have to go a long way vertically to make
up .004 laterally... I don't think this is really an option.

 

3) Bore that main more and machine a spacer. (I was not aware of this, but
apparently drag racers do this all the time? Comments?)

 

4) Use my other block and start over. (Sigh...)

 

I should know about the crankshaft condition Friday or Monday. Getting it
crack tested and checked.

 

New question:

I had thought about this before, but dismissed it.

Asked two other people and they said no way.

 

But. I'll ask again. How about side loading with lots of belts too tight on
one side?

 

I don't have this scenario, but was wondering. Can you trash a main bearing
due to accessory belt load?

 

FWIW,

Kirby
