What's the ft #s at the flywheel? Not the at the ground.. I need figures before the drivetrain does any reduction. long story short I need numbers to replace a typical SBC in front of a gearbox with a hydraulic motor......hillbilly way to cheat and get shuttleshift... I plan lathing/machining my own bell or modify something for direct drive. i'd have to guess nothing more then 200ft#'s, but it's just a ballpark figure, naturally the mid60's with flat top end of deck travel were higher, but i'm looking for an average. or at least a comfirmation. of various era's. i think #'s advertised are rearwheel hp/torque? edit i guess i'm looking for input ratings for a np435. searching high and low and can't find input ratings..
