Block Filler/Cement

Seems I'm turning to you guys/gals for help more and more. My latest dilemma is that I found a 454 block that has had all the machine work done on it and the guy I got it from told me it had been bored .60 over. Well my guy at the engine shop miked it today and it's .100 over, but that's not the problem. This is a four bold main block that seems to be in very good condition. Cam bearings have been installed and it seems ready to build. Now, I only paid a pittance for this block and bought it basically sight unseen, but my guy at the shop tells me that it has been partially filled with block filler. Not too full, just enough to give it some strength. It appears to be an epoxy base filler as it is very smooth and black in color and they told me it didn't appear to be cement based. I'd like to use this engine for street use, but want to remove the filler. Does anyone have any idea on how to remove epoxy base block filler?

Maybe good for 1/4 mile trips but not for street use.

Partial filled blocks are run on the street quite a bit. I would run an oil cooler.

You cannot get the filler out.

I hadn't thought about the oil cooler. You folks are the best. I feel much better about my purchase now. Maybe a high volume water pump and big radiator too? Thanks for all the input.

no need to go overkill on the radiator or the water pump, a good oil cooler will be more important/useful. I've seen people run a chevy with just a huge intercooler and no radaitor on the street.
