Re: hardblok
The drag racers use it quite a lot. But then, that bunch are also known to run without coolant. I'd have two concerns here, adequate cooling and eventual degradation and break-up of the filler.

Re: hardblok
Helped a friend replace several sleeves and then treat an aluminum 440 Mopar block with Hardblok that had been stroked to 512 + inches a few years ago. Strictly an all out race engine. I can't see anyone every having any success in using it in a street engine as you would have major destruction after a few miles.

Re: hardblok
I'm building an oem mopar 440 block, out to 540". Block is 60% Hardblock filled. I fully expect to use on the street/track days, for long periods of time. That being said, time will tell,(first time experience). This will likey make oil cooling, even more important. I have "heard" of many, using block partial fills, for street use. BYOB, but be wary. Cheers, roverman.
