Longer lifter?
Anybody know why I'd have one lifter longer than the other 15?
(352 cylinder #2)
This is my first attempt at an engine, so any thoughts would be welcomed.
65k on the engine and it looks to be previously untouched....but Idk if I can know for sure.
Thanks

My guess would be that a lifter went bad and someone just changed it and put the wrong one in it's place. It must have been close to the same internally to have worked. But don't think for one minute that FORD didn't do it. I have seen things inside of engines that should have sent the part to the scrap pile but they used it and it lasted most of the time. The most common things you see are copper plating on the small end of rods to compensate for poor machining. Also over size valve stems to make up for a bad guide bore. The best one I ever ran across was in a 1974, 460. The engine was pulled with around 70,000 miles because of a rod knock. When we pulled it apart #2 rod journal had two sets of oil holes in it. One where it was supposed to be going to the main bearing and another one going to nowhere which might have been OK if it had been de-burred, but it wasn't. And it ate the bearing way after the warranty was out.

Regardless of the reason, in your opinion, should i keep it as is (it ran like a top), or put the correct one back?
My gut says "put a new one in".

New one. Change out with entire Cam kits ... Cam, lifters, rods, and timing set. Looks to me like an different lifter all together. Is that the only odd ball? Chances are someone prior dropped the wrong lifter in and made the adjustment at the rocker. Which you may consider an entire head job while you are at it, new valves, guides, seals, have the machine shop chack the seats and change out the rocker arm assembly.
Mix and matching parts was common place prior to internet and easy (easier should I say) parts sourcing. Back way when I rigged some pretty strange stuff on my '66 Stang's 289 ... if JC Whit didn't list it and you couldn't find it in a junk yard, you did what you had to do.

Lifter
Others have also mentioned that Ford could have done it originally. When you think about the volume of parts used, the potential for a slightly longer lifter to accidently wind up in the wrong place isn't a far stretch.

Depends on what you are doing to the engine. Why were the lifters pulled to begin with? If you are leaving the cam in then reuse the lifters you have. Providing you know exactly which hole they came out of. If you mix them up your cam lobes will fail. 65,000 miles seems a bit light for an engine that old are you sure? If it were me I would put a new cam and lifter kit in it. That way you know it's all good.
There is zero visible wear on either lifters or cam.
I took everything out in sequence and organized it so whatever goes back in will go back where it was.
I know that mileage on these is always a bit touchy because the odometer just rolls back to zero. In that case, I look at wear on gas, clutch, and brake pedals.....as well as floor mat. Wear was extremely minimal. That leads me to believe the miles are actual.....or so I tell myself. Lol
