Gaterman GP-1023 Lifters Long Term Wear

I think it would be better to check the clearance when the tappet blocks are bolted down.

Good idea, maybe before and after, see what if any changes.

Plus under a valve lift event to rock the lifter over in the bore. Personally the whole exercise is a waste of time.

Yeah run flat tappets no issue

Think you have lifter noise now!!

I meant with a properly ground cam for them.

Not going to work unless the cams are locked into minimum end play needed for control in the rotations. Flat tappets are not the sulution.

Agreed, quality metal is what's needed, it has been mentioned in this thread more than once, and facts are facts, I have seen 2 sets of C's with 7k or less that the rollers were frosted just like the one in the OP, in contrast to a set of B's out of a 2006 with 52k that looked great. I have pics of all of them and anyone interested in seeing them, pm me your email address.

Everyone can stay in denial if they like, or choose to use a better quality USA made tappet and leave the frosting to Duncan Hines.

[clawdog60]

Ok, guess i will have to try the parts after a dip in the cryo chamber.

[clawdog60]

Doesn't look like we will be getting quality metal any time soon.

Timing chain is all that controls the cam end play in most all older motors, I haven't been in to any newer than 2005 motors to know about them.

Are you referring to HD twin cam motors here?

No, I should have been clearer, flat tappets in V8 motors. They lived with a fair amount of end play.

S&S premiums seem to be holding the QC standard,  BVBOB @ Razerback performance has a line of American made lifters as does GMR and Bob Wood. All of these mentioned seem to be holding their own as well.

[koko3052]

and at how many miles??

[06roadglide]

Jim is over 20k with his wood lifters.
I have a set of gmr, not that many miles on them yet but I'm not a bit worried about them. After talking to Steve about them I'm confident they will last.

Wouldn't that give a false reading?

It would be an operational reading. More important in my view.

Hmm, in regards the the V8s flat tappets, not too sure about that. If lobe angles are one direction and bore offsets to match, it would force the gear face to the block and act as the thrust surface. At least that's how I'd build the damn thing.
Ron

[06roadglide]

I know SBC solely relied on the timing chain, when you installed a gear drive you had to install a button under the timing cover to hold the cam gear to the block.

[rbabos]

Somebody explain to me how a chain can hold end play to about .002-.005?
Ron

[clawdog60]

I could have sworn their was a thrust plate?

I saw Jim's Wood lifters, they looked like new
