ARP Stud Details 3500 (LX9)

[neophile_17]

Hey guys,

I just ordered ARP main studs from WOT-tech and I'm a little unclear how the windage tray plays in. In the stock LX9 configuration the main caps are held in with double ended studs which space the windage tray out the width of a nut. The ARP studs do not space the windage tray out. Is this the correct assembly order: ARP stud-main cap-washer-windage tray-nut? Will there be proper clearance between the tray and the connecting rod as the crank spins?

What do I need to know and have when I take my block to be align honed? If I had to guess it would be block, caps, windage tray, and ARP hardware (Bearings?). The machine shop I found has a quality reputation but I doubt there are enough 660 race motors for them to have the specs memorized. Will I need new main bearings or a shorter timing chain after this?

Your experience is appreciated.

Sam

my machinist was going to drill and tap the ends of the studs, so the tray could bolt down to the ends of them. right now, there is no try on my car, but when I pull it back apart to put a new HTOB in, I'll figure out a way to get it back in there.

Is there not enough stud left over to put the tray on top of the ARP nuts and then another nut to hold the tray on?

I don't think there was, but I don't remember for sure.
