roller lifters with 2.8

wow, for all the info you post up I'm a little surprised you can't follow this one. Not once did I quote you or the photo you posted.

The Studs Ben sells are too long for this Original poster to use look at his pictures and posts to see why I'm not going to explain that again, Mach 5 posted up a DIFFERENT part number that would not be too long for the main's alone with 1 washer, I thought it would be a good option to use over double washer's since ARP recommends not doing that. BUT After thinking it over I'm also running a crank scraper and a windage tray so the shorter stud that Mach 5 posted is too short for me.

Sorry, still not quite following. Are the ARP studs too short?

Or are you referring to the picture I posted?

Which studs, ARP?

I'm quoting Ben, so yes I'm referring to the ARP studs that were posted. If they are shorter than what Ben has in his store then they will not work on an application with a crank scraper and windage tray which is what I'm running. But if your not running either then you'll be fine using those.

Those studs are not long enough for a windage tray. I wonder what ARP think of running a crank scraper, since that is a sheet of metal between the nut and the main. Would that act as a bearing as well with a washer on top of the crank scraper? For racing, a windage tray and crank scraper should be considered necessary.

Once I started to think about it I was wondering that, I guess that answers my question about using those.

[NateD4]

It really depends on the steel used for the windage tray and the heat treat it has. If it is a good quality steel and is thick enough you can load it up with preload and it'll be fine. If its a poor quality and hardness steel it'll deform and smash as cyclic loads are applied and the bolts will loosen as the washer smashes out.

Here is a set I had made that addresses this issue and allows use of the stock 3900 windage tray. These studs let me use the stock fastening method for the windage tray. No drilling required.

my own personal belief I won use a crank scraper the windage tray I like but not using for this motor on my daily. Ben I would drop a line to ARP and ask them. What if you used a thinner nut on the stud? I forgot to bring my studs with me to get a pic today Ill probably go tomorrow.

I will get a pic for clearance.. Im currently building another motor for my other car I will stop by the machine shop so I can grab a pic tonight.. Im running no windage tray or scrapper.

He is talking main studs, it just so happens a "head stud" fits our mains better since there is not an exact part that fits.

[NateD4]

Oops, thought you were talking main studs not head studs. I can have either made if you are interested.

[NateD4]

Which bottom end is on this engine? Is it a 2.8 style or 3400 style? With or without the windage tray? If you want custom studs I might either have a set or get a set made.

This thing looks mean!!! real freakin mean!

I was half way through your thread... I had a problem with my main studs. If you want a better part number that will have a better fit let me know its slightly shorter and is fully threaded. After talking to ARP they recommend not stacking washers as it acts as a bearing and reduces clamping load so they advised against it.

I'd be interested in those PN's since I was not too keen on stacking washers either hence why I still have factory main bolts.
