[Supras] (no subject)

[FauxZ]

I choose to keep all my other comments to you off this list as I'm sure most 
people could care less...  This statement that you repeat over and over 
again is not only vague, it's incorrect and it upsets me that this goes 
mostly quiet..  If you would reference a list of cars that have iron blocks 
and aluminum heads (such as EVERY supra built in the last 2 decades) you'd 
see that this statement means virtually nothing..

Everyone knows that Toyota released a service notice about the torque on the 
head bolts... we all know that the 7M can chuck a HG, and the problem 
compounds if you don't maintain the car..  Everyone here takes that into 
consideration when repairing or modifing the motor (or the should)...  I 
reccomend you build a bridge, and get over it.
