Solid roller lifter adjustment.
Two good things in one day!
First this new 434 gets great MPG. Then the second thing is the valve lash adjustment. I was thinking 4 road race track days, 240+ water temp, running it over 7000 RPM up near my 7500 rev limiter, Big beat the crud out of the valves solid roller cam .685/.714 lift, and 1526 miles since I even checked the .022/.024 valve lash at the 300 mile second oil change.
The intakes were right on and the exhausts were maybe .002 wider on four.
Good Crane gold stud girdle and Allen locking nuts is all you need
I'm out rodding around this whole week Because of our local "Reno Nevada Hot August Nights"

I sent you a nice e-mail.
You are right! 4 top dog racing mechs could set the valve lash and every one would have a different "Set lash"
I go for the hard to roll in and out. It puts a bite on the feeler gauge. for a .022 set a .024 will not go in and .020 is loose

Lady at work has a husband at T&D. I just don't have the money or the heads that need shaft rockers. I'm just boarder line with 60/40 Dart 227cc heads
This is my little rocker adjustment today

You've just been a regular test rat lately. 
I've always felt there's far too much negative propaganda out there about solids requiring rediculous maintainance schedules. If you've got the good stuff, and know what you're doing, it's no big...
Thanks for posting more evidence against the nay-sayers.

Dude, you seem pretty hostile in most of your posts. A feeler guage, with someone that knows how to operate it, is accurate to .001 or less.

when i say "you" i meant anybody not gkull specifically. My personal opinion is getting it perfect is not that critical. I can lash all of my hydraulic lifters in about 5 minutes by just bumping the engine several times.
I'm thinking i can lash mechanical lifters in about 30 min. I think i'm gonna go to mech in my next build. I don't think they're as much trouble as so many people make out.
Yep, I am challenging in a lot of my posts. I think it promotes good discussions.
gkull, I got your email, I can't wait to see some track video. I'm going to get mine set up too. You know you are a friend.

Not saying I'm Superman or anything, but we (two of us) used to do a full lash job in about 10 minutes between rounds without rushing. No, we didn't do it every round, but often enough that we probably could have done it blindfolded. It was no big deal, since we had the covers off every pass for inspection anyway. Of course, the balancer was indexed to maximize efficiency and we had a bump button under the hood, so you might call that cheating.

I just put a big 1/2 inch drive rachet to the crank bolt. It takes some strong pulls to rotate a tight 434 over with 11.8 compression. But I can check/set the valves in 10ish minutes also. The worst part is getting the tall valve covers off because all the things passing over them

I set mine in the spring and they are not touched again until I back them off in the fall. I also run the crane stud girdle and I set my lash .006 cold under specs.
I run a ford solenoid and have the one on the starter shorted out. I also have a hand held push button switch with a long wire and two aligator clips. You short across the ford solenoid with the aligator clips and then just bump the button to click the start.

I permanently wired a starter button under the hood to bump it over. Sure makes it sweet!
Solid rollers seldom need any adjustment..even big ones. When they get out of whack...something is dying.....not much point in adjusting it. It's going to die.
Not to imply .002 is out of whack. Usually it's a case of them all being fine except one or two and all of a sudden they are .005-.010 looser than the rest. Something is dying on those cases and it won't grow back.

Ya. if one is .010 loose, time to look at it. Remore starter buttons are a must; I have one on my firewall.

These were Crower Severe Duty solid rollers w/ HIPPO and I had somewhere in the vicinity of 6K miles on them, which is about what I expected to get out of them. I replaced them w/ newly rebuilt Morel lifters and will check again every few thousand miles, or when I hear more valve train noise.
Street running and idle time w/ solid rollers and attendant 600lb+ open spring loads and.700"+ lift = regular lifter replacement. It just goes with the territory....
