Re: Cast iron or Aluminum? I have seen a broken block. But it was from a piston. The piston ring was wrapped around the camshaft and the block around cylinder #5 was broken on the water jacket all the way down the cylinder.

Re: Cast iron or Aluminum? #84!!! uhgggg!!! can't breath!!!
what are these ?? shower heads!!!!
seriuosly, the aluminum block has a problem with it being able to maintain it's shape and avoid warping. i'm saying this from my own experience, i had ~60k miles of hard driving with no blower on my engine and when i tore into it , i found that some spots on some piston walls that still had the crosshatch, and other spots ( some on the same pistons) had severe wear .
the only scenario i could come up with is the block dforming under stress, and i could only emagine how long an aluminum block would last it it had a big blower , or worse yet having material removed for bigger liners.

My bores showed no signs of uneven wear with some pretty hard abuse.
One thing to watch in a stock motor is the wrist pins. With a press fit in the rod, once you start to bend them w/ severe cylinder pressures bad things start to happen. pistons get cocked funny and the bores take the beating.
I have no plans to go iron.

Re: Cast iron or Aluminum? 1dirtyZ, from what Jason at GWP says, you are right.
He said when you make just so much HP with the aluminum block, things start moving around too much in there... and not the way you like! <img border="0" alt="[guns]" title="" src="graemlins/gr_guns.gif" />

Re: Cast iron or Aluminum? What kind of computer will you use w/the 96's.It is my understanding that you cannot go with anything bigger than 50's with a ls1 comp. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
