why would you want too switch from the good stuff.to the cheaper..crap...that makes no sense..iron is king..you want to go to the cheap aluminum-plastic tank on o-rings...dont make sense to me.do you just think it looks prettier.

i would think gm..switched to the cheaper junk..so it would break or wear out faster..so they could sell more..it is like when harley..switched to the.aluminum
cheaper engines..

the iron engines..could be rebuilt..like ten times.as more and was like a rock.but too each there own..when the cheaper brake system fails and if you crash.remember..i told you so..

That's funny, I've had countless cast iron master cylinders fail, and only one aluminum unit fail
