I use the GPI and did not pull the crank or rebalance. They had a super sale black Friday... I purchased mine 7 months ago. They rate it at 1000 HP, but IMO the CR is too high AND the components are very light for this HP. My limit was set at 850 HP with LT, 800 with stockish ( two homemade front cats, rest is stock) exhaust. /Cunningham rates their drop -in at 1200? IMO the stock weight is VERY light for 850 HP... but I will admit I grew up racing 440 engines with hemi rods.
