those shocks are as adjustable as you could get bush! 4 progressive rate springs, high and low speed rebound and compression adjustable. the top spring is actually a "self saggind device" that is only used in the air to extend the crap out of the shocks. with any significant weight on them they bottom out to keep the ride height down. very good shocks!
as for the mod list............it has the stock bore, and stroke, but not for long. everything else has been modified or swapped out for the bigger/better/faster! it is still only a 400, but the next rebuild will involve a +8mm stroker crank, and bigger bore........results will be 14.5 compression and 510cc. i am debating going with a shorter crank and bigger bore to make a 470, only because it is much less of a rod angle than the +8 so it wont eat pistons. we will see what happens when the time comes for that.
