72 Demon slanty-to-340 Resto

No offense taken Jeff. I should have been more specific. However you described it for me. 450-500 hp or more, side stepping it all the time, beating the ever living dog **** out of it. Basically driving it like a ******* animal.

I however have seen and heard of cast crank flanges breaking on dirt circle track cars. Not sure if thats the constant on and of the gas loading against the crank, coupled with severe useage or not. Or the fact that they are the usual 350 chevys with a typical stocker cast crank.

If your combo isnt above 400 you should be fine w a cast crank just get it magnaflux checked for internal defects, get your rotating assembly balanced to minimize any vibration.

Jeff is right. At what cost? Is it so you can have bragging rights at the local sonic or other car hangout, or do you plan on hitting it with a 100 or 150 shot nitrous on a regular basis. Base it on what you intend to do with it.
