The iron duke is actually the 2.5 4cylinder engine and came with an isuzu 5sp that would prolly blow apart with a V8 but is still stronger than the stock auto
Gah, I was throwing the slang around, you know what I mean, the 2.8L V-6 that came stock in Fieros, and I WAS refering to the Muncie, the 3 speed auto should never be mentioned in the same sentance as Fiero...

I'm not surprised the LQ1 is giving you grief with that ugly tranny between it and the wheels =\ And the Muncie/Getrag CAN be driven with powerful engines, but have also been proven to make like Hiroshima after 6-10 clutch drops, even granny driving it you replace them every 15-20k. If you're honestly shooting for a 400hp performance build, look elsewhere, stocks are NOT suitable for this kinda application, trust me.
