I don't remember. 

But now son has decided to "upgrade" his old 454 truck engine, and has spent
more than $8000 on the engine at a local shop. I have grown too old for such
adventures anymore.

Now that the engine block has been bored .060" over and everything (and I mean
EVERYTHING, including aluminum heads) but the block has been replaced with shiny
new stuff, the engine just cannot run cool enough. There is an answer for this,
but I don't want to have to do it. But it may come to that.

I am open to suggestions.

years the crank had bent enough that the engine wouldn't turn with hand pressure
after assembly. Check with dial indicator and find it is bent .003". Return it
to grinder where they put it in the lathe and check it. They smack it hard with
a lead hammer and it is perfect. The engine ran for many years after that. I was
rather surprised that it was so easy.
