adding a windage tray

[SAC69]

I'll be installing a Canton T-pan soon along with a new oil pump & driveshaft. I'd like to also install a windage tray but this would mean replacing 4 main bolts with 4 studs to attach the tray. Will this create an issue with the torquing sequence of the crank? The original engine runs fine now (112k) and I won't be rebuilding it for 1-2 more years so I don't want to create an issue with bearing failure if I unload the torque on only 4 bolts. Is it best to wait until the rebuild?

Thanks for any info.

Not necessarily torque sequence, but clamping force would be my concern. Most likely, the new studs will require more torque than the other bolts. This might lead to slightly warping the main caps which could cause premature bearing wear.

i personally don't think it's worth adding until you do a rebuild and even then there seem to be a lot that argue it's worth then.

here is a pic of a canton windage tray in mine if at all interested.

Buckeye, That's a SBF, correct? Who makes that water pump?

Any reason not to just replace the other bolts at the same time? That would take care of your torque concerns.

To replace all the main bolts with studs would add another $75 or $100, I think I'll just wait until the engine's rebuilt to add the tray.

Plus you really need a line hone when adding studs. I believe it's a good choice to wait.

I believe its a good choice to wait as well. A modern, baffled oil pan takes care of alot of oil control issues that were a problem with the original pans and what windage trays were designed to help with.

As far as line-honing when switching from bolts to studs, it MAY be necessary but not always. It is however, very important to have your main bore alignment checked with the studs torqued to make sure everything is fine. When sending the block to the machinist for work make sure you include the studs you plan to use so they can check the bore alignment properly.
