superooo Posted September 23, 2016 Share Posted September 23, 2016 I have 3 motors worth of hydro lifters and rods, building an ea81, do i need to source new ones? Or what steps do i need to take to pick from these and install them, i read you have to put them back on the lobe they came from after theyve been used. Thanks. Hope this motor is done by Christmas Link to comment Share on other sites More sharing options...
superooo Posted September 23, 2016 Author Share Posted September 23, 2016 Rockauto.com has "mechanical" lifters but they look solid and my motor is hydro, pretty sure, cause i think one of the sets originally went to this motor. Thanks Link to comment Share on other sites More sharing options...
superooo Posted September 23, 2016 Author Share Posted September 23, 2016 Oh and kinda off topic but my dad being a v8 mechanic wanted me to ask if they made nylon wrist pin retainers for our motors like they do on Harleys and v8s, anyone know? Didnt think it warranted a new thread Link to comment Share on other sites More sharing options...
silverhelme Posted September 23, 2016 Share Posted September 23, 2016 I'm not for sure where you can source the lifters but if you install new lifters you should install a new cam also, If you don't odds are you will destroy the cam is short order if you mix and match. I have had several of the hydro motors and have had no problems with the hydro lifters, so what I would do is find the cleanest and best looking set with the least wear on the cam and install them as a set with the cam they are worn into and with the lifters in the correct positions. 1 Link to comment Share on other sites More sharing options...
superooo Posted September 23, 2016 Author Share Posted September 23, 2016 See its just a box full of lifters and rods, so i need to get all new and hae my cam ground and polished? Or what options do i have, no way of resurfacing? Link to comment Share on other sites More sharing options...
silverhelme Posted September 24, 2016 Share Posted September 24, 2016 I would say that if you want a reliable engine you only have a couple of options. One: new cam, new lifters and a proper breakin. Two: a complete used set with all the lifters in there original locations. You can substitute a reground cam for a new one but still would need new lifters and I don't know if lifters can be reground to put a new crown on the base. Here is a good article that explains some of the reasoning involved. http://www.hotrod.com/articles/check-flat-tappet-lifter-crown-lobe-taper-lifter-bores/ Link to comment Share on other sites More sharing options...
silverhelme Posted September 24, 2016 Share Posted September 24, 2016 I think the part # I sent you is wrong and should be 410517000. I found a couple online but be prepared for sticker shock if you can find anyone with some still in stock. Link to comment Share on other sites More sharing options...
