I just fed the Indy bore & stroke data into my Dyno2000 401 (390 crank) with fully ported 401-1K heads combo, and lost 24 HP and 1500 RPM off my peak.

More torque throughout the range, with a net gain of almost 90ft/lbs.

Still, nowhere near 800 HP.





Are they offering any smaller sleeves???

What is the deck height?

Will the AMC crank drop in?

My mouth is watering less over the aluminum crate motor!!!
(thank GOD!!!)
