Pushrod Measurements

Finished the pass side. Only .007" diff over there. So .017" total. I will check one final time once the heads are torqued down, lifter trays in and all that.
7.422 to 7.405 for 0 lash. Flat to flat.
Now to figure how much preload I want to run........and exactly how to deal with the gauge length. Seems to be splitting hairs.
redsilv, as long as you are on the base circle of the cam, I think you have got it!
BTW....what do you mean by pushrod length checker? I think this term gets used to be the same as an adj. pushrod.
This is a pain in the A$$, but actually rather fun and interesting once you get going. I'm thinking it would be neat to design some better tools for this. Would be simple.
Thanks for the coaching Z.

Just subtract 0.017" from your flat-to-flat measurements to get gauge length. It's only splitting hairs if you're running lifters with large plunger travel (ie, LS7 lifters). But if you're using lifters that have a very short plunger travel, then the difference of 0.017" between gauge length and flat-to-flat can make a big difference in the pre-load setting.

The one for LS engines (Adjustment Range 6.800 in. to 7.800 in.)

I just got done putting in the cam this evening and now to wait
on the pushrod checker to come
have any of you guys had trouble with the crank pulley
going all the way on? mine still needs about 1/4 inch to
set flush against the timing cover.![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)
Im not intentionally trying to change this thread
but this bothers me and i was putting alot of pressure on my
breaker bar and i got uncomfortable putting that much strain on the
old crank bolt (stock)
any advice?
