Block filler?

[Robert Lone]

Hey guys,

I've got a 4.3 engine block that I'd like to build as a spare since my dad and I both have those in our trucks. It has been strapped, studded, splayed, and filled. Really filled! Up past the freeze plugs! That'll never survive on the street.

I have (on several occasions) un-filled an engine block with the usual nail and punch and long-ass drill bit and it sucks. Is there a chemical (acid or base) that'll eat the block filler and not the cast iron? If not, who else has gotten this stuff out of one and how many chickins did you sacrifice?

Another DAQ,

Robert :tup:

Id say your probably better off finding a new block.

You are probably right but that wouldn't be any fun.

Does anyone know what block filler is made of? This one is filled with the water cured white powdery stuff.

Re: Block filler?

I filled my last stock block so that the block fill was 1/4 below the water pump passages.
I had zero heating problems with a Stewart warner stage 2 pump.

Now the motor is in a more stock truck with AC etc and zero problems.

Just use a good water pump and you will be fine.

Re: Block filler?

Someone started beating the filler out before I got the block. Once it's started it has to be finished from my understanding. Or can I just mix up a little and pour in on top to seal it back up and prevent the little white buggers from floating about aimlessly?

Yep just power wash it real good with a power washer to get rid of the loose stuff.

Then repour it. Try to use the same stuff they used in the first place.
If you do not know for sure what kind it is don't worry it will be fine.
