ok guys got me a pushrod checker and this is what i came up with

6.800+10 turns is .5 so that is 7.300 so my ? is how much preload do i need????

if i need .050 preload then i need 7.350 pushrods rite???
if i need .100 preload then 7.400 is what i need

so how much preload do i need to run so it dont sound like a bunch of ninja fightn under my hood!!!!

Your method seems correct. What lifter are you running? <<< That will determine the proper amount of preload needed.

.050 - .080 is great. You should end up pretty quiet if you end up anywhere between 1 to 1.75 turns past zero lash to reach full tq spec.

I just went through this and we ended up a little less than 1.75 turns (about 1 2/3). It is nice and quiet with this setup.

My setup used 7.375 pushrods. I tried 7.400 and they ended up with 2.25 turns to full tq. 7.350 would have put me right on 1 full turn. I was told better to be slightly on the high side then on the low side.

Worked for me..... Good Luck!!!
