Default Johnson 2116 Lifter Question

Does anyone know if it is normal for these to require about .100 longer pushrod than LS7 lifters or even 2110’s? I went to order my pushrods and the guy told me that the length sounded too long to him for my setup. I have LSX with pistons .014 in the hole, TFS255 heads, CHE LS3 rockers and Johnson 2116 lifters. Just looking for any experience with the 2116’s. We measure them at 7.930
.. Thnx

Yes you will need longer. How much I'm unsure of.
Just last night I had my 2116 and LS 7 lifters with a pushrod sitting in them and the 2116 was shorter in overall height.

I know mine were on the long side but you would be best off assembling everything and measuring for pushrods. Unless you are going with a known grind and lifter, you should always mock it up and measure then get the correct length.

Thatís exactly what we did. Just the guy I was ordering the Mantons through(not Manton) told me that was too long on my combination and had me doubting what we had done.

7.813 and 7.826 that's what my rods spec'd out at with the 2116 a/o lifters. That's including preload.

Well my Mantons came in at something like 8.063/8.048 on TFS 255s. So many things influence pushrod length. If you have measured properly, don't worry about what someone else is saying. Too many people think "oh it's an LS so it needs 7.4" pushrods." Yeah that math only truly works if you are doing a cam swap with the same lifters and base circle on the cam. You have changed much more than that so go with your numbers and verify when you receive your new pushrods.

Exactly, the only true way to know is to measure. Trust me my measurements were off the first 2 times I measured I have no idea really how, took me a third time to get it correct with zero lash. Now I have a set of manton rods just laying in my garage.
