Need help identifying pistons in iron 6.0
Need help identifying pistons in iron 6.0 I recently bought a brand new motor, supposedly built for boost...however it has 243 heads and flat top pistons...no valve reliefs. Can someome help me identify what they are?
Part numbers etched in the tops are
L164 21
81077F A5 401
Thanks!

I never heard of some one running flat tops on boosted apps. The flat tops and 243 heads will give it a higher compression, if the heads werent work over.. Just take off the oil pan flip it upside down and look the name should be ecthed on there.
Thanks! My thoughts exactly....that's why I said "supposedly built for boost". It obviously wasn't with 243 heads and flat tops. I will be pulling the pan later in the week when I get some more time to mess with it.
