ok, im doing my MS4 swap, wondering what gears to go with. ive been planning on 410s but just wondered if i should go lower than that. not DD, dont care about mpg, just want as much performance as possible but still good driveability. also i ordered HS 1.7 adjustable roller rockers, how much adjustment do these give? i know i obviously still need the right length pushrods, but just curious as to how close they need to be...thanks for any replies!!

Do they come with the pushrods? If not, there is a way to determine the correct pushrod length/adjustment. I worked mine out with the Cranes on the workbench by obtaining the best wipe and then measuring the adjustment nut position such that when I put them on the car I knew where to set the rocker to measure for the pushrod.

Where is the adjustment nut on the YT's, it is at the stud or at the pushrod?

they don't come with pushrods, but the adjustment nut is at the pushrod...

So the fulcrum bolts down hard and the preload on the lifter is set by the adjuster? Then you can check the wipe, and once you have that measure for the pushrod.
